fix test relevancy and add test IDs
    
    Certain test phases are not relevant for RHEL-8 and they fail because
    of that fact.
    
    Certain tests still require the setools package, which
    is not really needed for their successful run.
    
    Many tests lack the FMF (generated) ID.
    
    Several tests still contain the TIPfail tags (related to the Test
    Improvement Project which was discontinued a long time ago).
    
    These issues should be fixed now.
