gdk: exclude MOD1 from the virtual modifier mapping

Browse Source 
which effectively nails down the MOD1 == ALT assumption that is valid
in all other parts of GTK+. After the modifier abstraction fixes for
OSX, the virtual mapping is now (correctly) used in more places, and
caused problems with the common default PC keyboard layout on X11 that
colocates ALT and META on the same key.
