wayland: Only send full sequences of touch events to clients

If input happens to be grabbed somewhere along the shell, and ungrabbed
while a touch operation is ongoing, the wayland bits will happily start
sending wl_touch.update events from an undeterminate point, without
clients having ever received wl_touch.down for that id.

Consider those touches grabbed for the entirety of their lifetime, if
wl_touch.down wasn't received by the client, no other events will.</pre>
