    services: herd: Fix matching ok responses from shepherd service.
    Previously the match expression case for a successful response
    (where error is #f) required that the result component contained a list 
with a
    single element.
    As far as I see when looking at the responses from the shepherd, this is not
    normally the case. Therefore, to avoid treating successful responses as
    errors, make the match requirement more permissive, accepting any value.
