Get us closer to running the tests
    
    This commit adds as many BuildRequires as possible to get to run the
    tests at build time.
    
    Unfortunately, 3 are still missing from Fedora. They are now added too,
    but commented out so the build doesn't fail, providing an indication of
    what is missing.
    
    This commit also fixes the way tests are run, to be in line with what
    upstream documents in their contribution documentation.
