Carlos Garnacho c5ac80be2b gdk/wayland: Do not use xdg_wm_base.ping serials as "user input" serials 
Ping/pong serials are not meant to be interpreted as user input serials
(e.g. those given back later to the compositor on grabs). As a matter
of fact, Mutter uses a different count (i.e. timestamps) in these, so
using these serials may confuse the compositor into denying certain
operations like DnD.
