[virt-tools-list] [virt-manager PATCH v3 3/3] osdict: adapt latest_os_version() to ignore "-unknown" distros

[Fabiano Fidêncio]

As some enterprise distros adopted the "unknown" approach in osinfo-db,
and those usually support different versions at the same time, there may
be different "unknown" entries (like rhel-unknown, rhel-8-unknown,
rhel-7-unknown, and so on) for the very same distro.

This situation can easily happen when some ISO matches, for exmaple,
"rhel-unknown" and then the latest one selected would be
"rhel-8-unknown".

In order to avoid this situation from happening, let's just ignore the
"unknown" entries when calling latest_regex().
