wayland: Do not poll the Wayland socket for events

Browse Source 
Since Cogl also polls on this file descriptor we can get into situations
where our event source is woken up to handle events but those events
have instead been handled by Cogl resulting in the source sitting in
poll().

We can safely rely on Cogl to handle the polling on the event source and
to dispatch those events.
