dnd: Only handle touch events in wayland

Browse Source 
There are serveral issues around touch passive grab and touch/pointer doubly
handling to use these on X11, so we stick to single-touch/pointer there.

Cherry picked from commit 60ccdc2deb

Closes: https://gitlab.gnome.org/GNOME/gnome-shell/issues/1015

// set up by Mutter will make us see first the touch events
// and later the pointer events, so it will look like two
// unrelated series of events, we want to avoid double handling
