[at-spi2-atk] Add an atexit handler to remove the D-Bus socket

    Add an atexit handler to remove the D-Bus socket
    
    We should try not to leave stale sockets and their directories when exiting.
    They are removed when calling atk_bridge_adaptor_cleanup, but gtk does not
    currently call this function when exiting, and there is not a good place
    to call it from gtk.
