x11: Mark backing_store as NotUseful when creating windows.
This can give some performance boost, and save some resources, as there's no
reason to keep a copy of an SDL window's contents on the server: most SDL
apps are redrawing completely every frame, and the API allows for expose
events to tell an app a redraw is needed anyhow.
(And compositors are free to ignore this setting if it makes sense to do so,
according to the Xlib docs.)
Reference Issue #3776.
