            Log:
            test if systemd-run works inside systemd-run service

Recently, debugging of unrelated systemd issue revealed that SELinux
prevents a successful execution of systemd-run inside systemd-run
session. The TC reproduces the situation.

In order to support the above-mentioned scenario, I believe that
SELinux policy should allow the dbus-broker to read/write from/to
UNIX stream socket owned by the systemd session. The TC looks for
appropriate policy rules.

The TC covers RHEL-61928 and RHEL-62185.
