Remove _NET_FRAME_EXTENTS on shutdown.

Browse Source 
After we exit there are no window decorations therefore frame extents
are meaningless.

We could be left with parts of the window being the wrong opacity if the
property is left intact and a compositing manager configured to draw
decorations with a different opacity to the rest of the window is still
running.

Remove the _NET_FRAME_EXTENTS property from all windows when we shut
down to prevent windows from being drawn incorrectly after we're gone.
