reftests: Always wait for rendering to settle

We wait for a few 100ms for rendering to settle in various WMs. So far
we only did that for windows that were controlled by the WM (aka
toplevels).

With modern compositing gnome-shell however, this now also applies to
override-redirect windows, so we now wait there, too.

This makes the reftests a lot slower, but they now actually work when
running make check in gnome-shell.
