wayland: Start up the grace Xwayland period right after starting Xwayland

Browse Source 
There may be cases where a X11 client does not spawn any X11 windows (eg.
simple clients like xinput --list, or xlsclients), in this case the Xwayland
server would remain running until X11 windows happen to come and go in the
future.

Firing the shutdown timeout on restart caters for this, and would be undone
if the client maps X11 windows.
