xserver-nodm: Disable dbus-wait as it causes users too much confusion
In the event the xserver fails to start the dbus-wait has to time out and
this causes many users a lot of confusion. If we wish to reinstate this,
we need to find a safer mechanism to do it where X failing to start cancels
the timeout (sends a dbus event at that point?) The comments are left in the
file as an example in case some user does wish to enable is.
