Miloslav Trmač 1d7ec1ef5f Use the config digest to compare images loaded/pulled using different methods ...

Historically, non-schema1 images had a deterministic image ID == config digest.
With zstd:chunked, we don't want to deduplicate layers pulled by consuming the
full tarball and layers partially pulled based on TOC, because we can't cheaply
ensure equivalence; so, image IDs for images where a TOC was used differ.

To accommodate that, compare images using their configs digests, not using image IDs.
