Update/fix some urls
- Removing OpenStack variant and urls from debian-testing
- Update aarch64, x86_64 and remove i686 qcow2 images url from p10 and p9 alt linux
Found it running OSINFO_DB_NETWORK_TESTS=1 make check
and last run only had issues with opensuse tumbleweed but those seem to be a bad redirection on their server side as the images are there.
