test if systemd-sleep can getattr() a partition
Hibernation which uses a swap partition instead of a swap file fails
because SELinux prevents systemd-sleep from getattr operation on the
swap partition. This is a common configuration, which means that
SELinux policy should allow it.
The TC does not reproduce the scenario, it only looks for appropriate
policy rules.
The TC covers BZ#1928539, BZ#1912385, BZ#1926536.
