commit afc57a61209f806581c3c6ca472077fbcba835ec

    Include previously unknown error codes in Torperf results.
    
    As discussed on #34031, we should avoid keeping a map of known failure
    types in the sources and simply put together the error code in the
    format we want.
    
    This patch implements that change.
