I always wondered how we should express this situation: should we keep
both dependencies? For example, if shadow dropes the dependency on 4.14,
then we'd drop it from podman too; but then we'd be missing the one on
3.17 as inherited from libsecomp...

But anyway, there's no good soltion...

Thanks for fixing my mess! ;-)
