xwayland: zalloc the x11_data_sources

The wrapped weston_data_source struct has new fields which were left
uninitialized, so its access is unreliable.

The data source in xwayland/dnd.c should be eventually setting the
drag-and-drop actions, but it is a lot more incomplete than that
(read: completely), so falls out of the scope of this patch.
