osdict: expand the "unknown" check for any distro

Currently osinfo-db has "unknown" entries for fedora, opensuse and
asianux. Considering this list may grow even more at some point, let's
just make the check more generic and use it for all of them instead of
keeping it for fedora only.

Changes have also been done in urldetect and tests_url, as those also
used latest_fedora_version().
