    sim: testsuite: improve parallel test processing
    
    The current logic limits itself to a maxdepth of 4 when looking for
    results.  This wouldn't be a problem if cris didn't have a testsuite
    at a depth of 5 which we end up ignoring when summarizing.  Rather
    than bump the number from 4 to 5, rework the code so that we gather
    the exact set of tests that we tried to run.
