    tests/runner: Remove support running tests as an X11 WM
    
    This hasn't worked for a while, since the test always runs the nested
    backend, meaning it's a Wayland compositor. To unblock testing window
    management in combination to monitor changes, lets remove the
    unreachable X11 WM paths, so that we can start using virtual monitors.
