Add another new Cockpit join complete needle
    
    This one from ppc64le test. The difference between all the
    recent needles here is the amount of white space between the
    'Domain' and 'domain.local'. I don't want to change it to two
    match areas as there's a chance we may get a false positive
    match when the join actually failed (it may match on 'Domain'
    in the right place, and 'domain.local' somewhere else just as
    part of the system's hostname). I suppose if this keeps happening
    we could try two match areas but include some white space to the
    left of 'domain.local' to avoid matching on it as part of the
    hostname...
