xwayland: handle set_override_redirect events

Browse source 
This is needed to allow X11 applications to create surfaces as
non-override_redirect and then change them to override_redirect later

Without this gitk-menus and rofi are treated as xwayland-views with
associated server-side-decoration and forced positioning.
