feat: official Debian 11 compatibility (#176)
Introduce Debian 11 compatibility Based on CIS_Debian_Linux_11_Benchmark_v1.0.0 After review, here are the notable changes : - Harden /var/log more (noexec,nodev,nosuid) - Harden /var/log/audit more (noexec,nodev,nosuid) - Harden /home more (nosuid) - Disable cramfs - Fix 5.3.4_acc_pam_sha512.sh - Deprecate Debian 9 and remove useless docker images NB : more audit log rules have been introduced and will be inserted in the checks later Fix #158
