ewmh: screen_change: fix off-screen geometries 

When moving a fullscreen/maximized client to a smaller screen or with
different Y offset etc, its offset was not handled properly.

This moves it first into the new area, and then makes sure that its not
off-screen.  The latter should not happen, because the width/height is
adjusted before.
