extensionPrefs: Ensure up-to-date release version in metainfo

It's easy to forget to add a new <release> tag to the metainfo when
doing a new release.

Address this with an additional test if appstream-util is recent
enough to include the new validate-version command, so distcheck
fails when the metainfo wasn't updated.
