[GdkScreenX11] Add heuristic for pre XRandR 1.3 drivers

Browse Source 
Currently gdk_screen_get_primary_monitor just returns the first monitor,
in this case but both the panel and now gnome-shell use an additional
heuristic to prefer LVDS as primary if present.

Move this heuristic to gdk_screen_get_primary_monitor to avoid duplicating
it all over the place.

The fallback heuristic is also used when no primary output is set.
