Subject: test if tlp can search /var/lib/snapd/


A lot of reported BZs revealed that SELinux prevents the tlp processes
from searching (syscall = newfstatat) under the /var/lib/snapd directory
when the snapd package is installed. The TC reproduces the situation.

Based on the last comment in BZ#1888699, I believe that SELinux policy
should dontaudit the access. The TC looks for appropriate policy rules.

The TC covers BZ#2221019 and its duplicates.
