[at-spi2-core/wip/carlosg/x11-session-checks: 3/3] Only use x11 device event controller implementation on X11 sessions

    Only use x11 device event controller implementation on X11 sessions
    
    A wayland compositor would be impervious to the actions performed
    there, so it only could only partially work with other X11 clients.
    That doesn't seem like the intended effect.
