Sync role.py from testrole to the other ones.

Let’s keep them in sync from now on.
roled: New persistent option for debugging
roled: Terminate after some inactivity time without beeing used

After the rolekit service has been started roled is active and is not terminating automatically again. Calling timeout_restart after start is activating the timer in slib.dbus which is taking care on this.
Add d-bus service file to the RPM spec
