    session: Don't leak remote greeter interface
    
    XDMCP login screens get a "Remote Geeter Interface" exported over
    the bus connection (so the login window can provide a Disconnect
    button).
    
    This interface is getting leaked when the session object is disposed,
    leaving the bus connection itself undisposed, which causes an fd
    leak.
    
    This commit plugs the interface leak, and thus the fd leak.
