    Don't return X2Go Servers that are actually down, currently.
    
        The X2Go Servers get probed via a short portscan on the remote's SSH port. If
        that portscan fails, another remote X2Go Server is chosen from the
        list of available server (if any). This portscanning functionality
        can be switched off via "default-portscan-x2goservers" in x2gobroker.conf
        or via "broker-portscan-x2goservers" per session profile. (Fixes:
        #692).
