    Bug 22283: Linux 7.0a4 broken after update
    
    Improve our torrc fixup code to remove all ControlPort and SocksPort
    lines that contain a Unix domain socket, and execute the fixup one
    more time. This corrects a problem where the torrc of alpha channel
    users who transitioned from Unix domain sockets to TCP was left
    with ControlPort and SocksPort lines that contained bad paths (the
    parent directory for the Unix domain socket did not exist).
