On systems where /etc/sudoers.d might be updated often by some automated means, this
check might raise a critical when a previously present file (during the ls) is no longer
present (during its attempted read), so before raising a critical, re-check that it
does exists first.
The 99.1.3_acc_sudoers_no_all.sh script can sometimes timeout
on servers where /etc/sudoers.d/ has thousands of files.
This patch makes it run roughly 5x faster, as tested on a
server with 1500 files in sudoers.d/.
Closes#167.
