    Harmonize headers between both dg-extract-results scripts
    
        The header of the python version looked like:
        Target is ...
        Host   is ...
        The header of the bash version looked like:
        Test run by ... on ...
        Target is ...
    
        After this change both headers look like:
        Test run by ... on ...
        Target is ...
        Host   is ...
    
        The order of the tests is not the same but since dg-cmp-results.sh it
        does not matter much.
    
    contrib/ChangeLog:
    
            * dg-extract-results.py: Print the "Test run" line.
            * dg-extract-results.sh: Print the "Host" line.
