    tests: Fix performance-threaded test when run for zero seconds
    
    When running the test with `-s 0` it would previously crash. Fix that,
    and make it so that it only does a single test run in that case.
    
    This will be useful in an upcoming commit for smoketesting the test to
    avoid bitrot.
