Carlos Garnacho 8509a07a08 wayland: Set the master device on the drop-side GdkDragContext 
And force the ungrab on it, instead of the slave, in the case of
local DnD drop. This avoids confusions on the pointer events spawn
from DnD, as GDK doesn't think anymore those are from a slave device.
Most namely, it fixes the stuck grab when finishing DnD on the
same app it was started from.
