            Log:
            test if boothd can talk to kernel via UNIX socket

A recent booth + selinux-policy testing revealed that SELinux
prevents the boothd processes from reading the /run/systemd/userdb/
directory and connecting through the io.systemd.DynamicUser socket
stored in it. The TC reproduces the situation.

In order to support the intended boothd functionality, I believe that
SELinux policy should allow these actions. The TC looks for appropriate
policy rules and file context patterns.

The TC covers RHEL-57104 and RHEL-58060.
