Theses are from a031b83a (Initial checkin from CRI-O repo,
2017-11-01), but they're CRI-O's logos and not libpod's or podman's.
We still use CRI-O's logos in a few places, but since a031b83a all of
those references have used cdn.rawgit.com URLs pointing at the CRI-O
repository. That means there's no need to keep local copies of
another project's logos here.
