            Log:
            test if chronyc can talk to the restricted chronyd via socket

Recent selinux-policy + chrony testing revealed that SELinux prevents
communication between chronyc and the restricted chronyd service. The
TC reproduces the situation.

In order to enable this use case, I believe that SELinux policy
should allow the communcation in both directions. The TC looks
for appropriate policy rules.

The TC covers RHEL-82299 and RHEL-82308.
