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.
