bugfix: COPR testing

The COPR repos had another change in url naming. Because of it, directory index listings are downloaded as index.html for various arches. The 'mv' shell command refuses to overwrite them, which makes the pipeline fail. It's apparently problematic to filter out these using regexes, so let's just get rid of these files.
