[WIP] Verify images in manifest list are not dangling and pruned

[rhatdan]

Vendor in latest containers/common

Currently if you create an un tagged image and add it to a manifest list, podman image prune will remove the image, and leave you with a broken manifest list. This PR removes the image from dangling in this situation and prevents the pruning.

We have seen this trigger issues with RamaLama which is creating manifest lists in this manner, and then users pruning the images.

Verifing: containers/common#2360

Does this PR introduce a user-facing change?

Wrt. cockpit tests: The log shows a crash on podman rmi localhost/test-hello:latest. The full trace is huge, it starts with this:

panic: runtime error: invalid memory address or nil pointer dereference

As your tests don't fail other than this "tree is dirty, please run 'make vendor'" in postinstall, please let me know if you need help with reproducing. But as this is still "WIP", I won't spend much time on this for now.
