xwayland: Warn when autoclose-xwayland is not usable

Browse Source 
The experimental feature "autoclose-xwayland" requires a couple of
prerequisites:

1. Be able to (re)start Xwayland on demand, i.e. with systemd
2. Xwayland must support the terminate delay

Add a warning message if "autoclose-xwayland" was requested but any of
those prerequisites is not met.
