logind: allow greeters to take over VTs
Make sure a greeter can forcefully spawn a session on a VT that is in-use. A recent patch prevented this (this used to be possible for all session types) as it is highly fragile. However, as it turns out, greeters seem to rely on that feature. Therefore, make sure we allow it explicitly for greeters.
