Not check requires/buildrequires for existing koji tags
    
    When we're going to add a new module build tag into tag's inheritance
    data, we check existing module tags in inheritance first, previously
    we filter these module tags with requires and buildrequires, tags not
    match the requires/buildrequires will not be considered as old tags of
    the new module build. That is incorrect, we should have only one
    one combination of NAME & STREAM in one koji tag, which means we should
    not filter out the module tags that belong to the same NAME & STREAM but
    with different requires or buildrequires.
