refactor: is_kernel_option_enabled (#267)

Current "is_kernel_option_enabled" function is doing many things, like checking for a kernel option AND checking a kernel module state AND checking if it is disabled
We split it in different functions:
        - is_kernel_monolithic
        - is_kernel_option_enabled -> check for a kernel configuration in the running kernel
        - is_kernel_module_loaded -> check if a module is currently loaded
        - is_kernel_module_available -> check if a module is configured in all available kernel configs
        - is_kernel_module_disabled   -> check if a kernel module is disabled in the modprobe configuration

Also:

- update its behaviour to debian 12 CIS recommendation, to check if a module is "available in ANY installed kernel"
- fix "disable_usb_storage" to look for correct module name once loaded : issue #249
- the associated checks now check separately if the module is loaded, and if it is configured
- for checks about kernel module presence, the "apply" function now manages to disable the module in the modprobe configuration (if kernel not monolithic) (but still wont unload it)

+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each

+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this

+Each hardening script can be individually enabled from its configuration file.
+For example, this is the default configuration file for `disable_system_accounts`:
+
+```
+# Configuration for script of same name
+status=disabled
+# Put here your exceptions concerning admin accounts shells separated by spaces
+EXCEPTIONS=""
+```
+
+**status** parameter may take 3 values:
+
+- `disabled` (do nothing): The script will not run.
+- `audit` (RO): The script will check if any change should be applied.
+- `enabled` (RW): The script will check if any change should be done and automatically apply what it can.
+
+Global configuration is in `etc/hardening.cfg`. This file controls the log level
+as well as the backup directory. Whenever a script is instructed to edit a file, it
+will create a timestamped backup in this directory.
+
+
+# RUN MODE
+
+`-h`, `--help`
+:   Display a friendly help message.
+
+`--apply`
+:   Apply hardening for enabled scripts.
+    Beware that NO confirmation is asked whatsoever, which is why you're warmly
+    advised to use `--audit` before, which can be regarded as a dry-run mode.
+
+`--audit`
+:   Audit configuration for enabled scripts.
+    No modification will be made on the system, we'll only report on your system
+    compliance for each script.
+
+`--audit-all`
+:   Same as `--audit`, but for *all* scripts, even disabled ones.
+    This is a good way to peek at your compliance level if all scripts were enabled,
+    and might be a good starting point.
+
+`--audit-all-enable-passed`
+:   Same as `--audit-all`, but in addition, will *modify* the individual scripts
+    configurations to enable those which passed for your system.
+    This is an easy way to enable scripts for which you're already compliant.
+    However, please always review each activated script afterwards, this option
+    should only be regarded as a way to kickstart a configuration from scratch.
+    Don't run this if you have already customized the scripts enable/disable
+    configurations, obviously.
+
+`--create-config-files-only`
+:   Create the config files in etc/conf.d
+    Must be run as root, before running the audit with user secaudit
+
+`-set-hardening-level=level`
+:   Modifies the configuration to enable/disable tests given an hardening level,
+    between 1 to 5. Don't run this if you have already customized the scripts
+    enable/disable configurations.
+    1: very basic policy, failure to pass tests at this level indicates severe
+        misconfiguration of the machine that can have a huge security impact
+    2: basic policy, some good practice rules that, once applied, shouldn't
+        break anything on most systems
+    3: best practices policy, passing all tests might need some configuration
+        modifications (such as specific partitioning, etc.)
+    4: high security policy, passing all tests might be time-consuming and
+        require high adaptation of your workflow
+    5: placebo, policy rules that might be very difficult to apply and maintain,
+        with questionable security benefits
+
+`--allow-service=service`
+:   Use with `--set-hardening-level`.
+    Modifies the policy to allow a certain kind of services on the machine, such
+    as http, mail, etc. Can be specified multiple times to allow multiple services.
+    Use --allow-service-list to get a list of supported services.
+
+# OPTIONS
+
+`--allow-service-list`
+:   Get a list of supported service.
+
+  
+`--only test-number`
+:    Modifies the RUN_MODE to only work on the test_number script.
+    Can be specified multiple times to work only on several scripts.
+    The test number is the numbered prefix of the script,
+    i.e. the test number of 1.2_script_name.sh is 1.2.
+
+`--sudo`
+:   This option lets you audit your system as a normal user, but allows sudo
+    escalation to gain read-only access to root files. Note that you need to
+    provide a sudoers file with NOPASSWD option in /etc/sudoers.d/ because
+    the -n option instructs sudo not to prompt for a password.
+    Finally note that `--sudo` mode only works for audit mode.
+
+`--set-log-level=level`
+:   This option sets LOGLEVEL, you can choose : info, warning, error, ok, debug.
+    Default value is : info
+
+`--batch`
+:   While performing system audit, this option sets LOGLEVEL to 'ok' and
+    captures all output to print only one line once the check is done, formatted like :
+    OK|KO OK|KO|WARN{subcheck results} [OK|KO|WARN{...}]
+
+`--allow-unsupported-distribution`
+    Must be specified manually in the command line to allow the run on non compatible
+    version or distribution. If you want to mute the warning change the LOGLEVEL
+    in /etc/hardening.cfg

+A word about numbering, implementation and sustainability over time of this repository:
+This project is born with the Debian 7 distribution in 2016. Over time, CIS Benchmark PDF
+has evolved, changing it's numbering, deleting obsolete checks.
+In order to keep retro-compatiblity with the last maintained Debian, the numbering
+has not been changed along with the PDF, because the configuration scripts are named after it.
+Changing the numbering might break automation for admins using it for years, and handling
+this issue without breaking anything would require a huge refactoring.
+As a consequence, please do not worry about numbering, the checks are there,
+but the numbering accross PDFs might differ.
+Please also note that all the check inside CIS Benchmark PDF might not be implemented
+in this set of scripts.
+We did choose the most relevant to us at OVHcloud, do not hesitate to make a
+Pull Request in order to add the missing script you might find relevant for you.
