Client: Set window geometry for xdg-shell v6 and stable

Eventhough, according to the protocol spec, it should work perfectly fine
without setting the geometry, gnome-shell 3.28.2 chokes on it and
applications get stuck in the upper right corner and can't be moved.

Qt seems to be the only toolkit left that doesn't set the window geometry, so
let's just do it the simple, though somewhat incorrect, way.

The downside of this patch, is that the unset window geometry used to include
subsurfaces that extended outside the parent surface, but here we just set it
to the frameGeometry of the window.
