gdkdrop-x11: Use the preferred action if possible

Browse Source 
The XDND suggested action is a relic from when the source would control
the action for a drop.  With the new GtkDropTarget the target decides
the action (not the source).  That means the all of the returned
results from the ::enter and ::motion handlers will be unexpectely
ignored. Prefer to use the preferred action over the x11 suggested action.
