GHOST/Wayland: remove keyboard modifier mismatch warning suppression 

Detecting when to show warnings about GHOST/XKB modifier
mismatches was rather involved, remove the check as it's
unnecessary for Gnome-Shell >= v43.

Older versions of Gnome-Shell will show warnings on window activation
with modifier keys held.

* This has been fixed for GNOME 43. Keep the workaround until support for gnome 42 is dropped.
