GTK 3.20 compatibility: switch to gdk_seat_grab.

Browse Source 
gdk_device_grab and all its preparatory faff are now deprecated, and
gdk_seat_grab is the new thing. Introduce yet another branch to all
the ifdefs for keyboard-grabbing. On the plus side, at least it's
slightly simpler than the GdkDevice business.
