logout-greeter: Simplify shutdown check
Shutdown functionality was moved out of ksmserver to make that more X11 only. We moved to a wrapper plasma-shutdown that has more generic calls, including telling ksmserver to close gracefully.
org.kde.Shutdown is a shortlived program that only is alive whilst we are trying to perform a logout. Querying the name should suffice.
