Scripts: Workaround deprecated parse_version

Different approach from #3579

Instead of completely ddropping the deprecated path, support the new
path and the old path using python try-except import exceptions.

This allows us to continue using old packages in CI, while supporting
the future API once pkg_resources gets deprecated and removed. Best of
both worlds.
