            Log:
            test if power-profiles-daemon can watch /sys/firmware/acpi/

One of the reported selinux-policy bugs revealed that SELinux
prevents the power-profiles-daemon from watching the /sys/firmware/acpi
directory. The TC only reproduces the situation when the right HW
is available.

In order to support this functionality, I believe that SELinux
policy should allow this access. The TC looks for appropriate
policy rules and file context patterns.

The TC covers RHEL-105423.
