wayland: wayl_win_destroy(): unmap windows before destroying

Browse source 
This will trigger e.d. keyboard_leave() and wl_pointer_leave() events,
which ensures there aren't any references to the destroyed window from
the global wayland struct.

Call wl_display_roundtrip() to trigger those events *before* we
destroy the window.
