You can't really restart dbus in a systemd system...  However, the
problem seems to be the endpoint stops listening.  systemd-logind is
still running but strace -p shows it no longer responds when something
contacts the end point.  If you restart it, it will listen for a while
before stopping again.

The script simply detects the dbus timeout and restarts the service.
