            Log:
            test if boothd can connect to systemd-machined via socket

Recent selinux-policy + boothd + systemd-machined testing revealed
that SELinux prevents the boothd process from connecting to the
systemd-machined process via the /run/systemd/userdb/io.systemd.Machine
socket. The TC reproduces the situation.

In order to support the boothd and systemd-machined cooperation and
to avoid unnecessary SELinux denials, I believe that SELinux policy
should allow the access. The TC looks for appropriate policy rules
and file context patterns.

The TC covers RHEL-75471.
