Backport of #1505

@Luap99 @flouthoc PTAL

When looking up an image by digest, make sure that the entire repository
of the specified value is considered.  Previously, both the repository
and the tag have been ignored and we looked for _some_ image with a
matching digest.

As outlined in containers#1248, Docker stopped ignoring the repository with
version v20.10.20 (Oct '22) which is a compelling reason to do the same.

To be clear, previously `something@digest` would look for any image with
`digest` while `something` is entirely ignored.  With this change, both
`something` and `digest` must match the image.

This change breaks two e2e tests in Podman CI which relied on the
previous behavior.  There is a risk of breaking users but there is a
strong security argument to perform this change:  if the repository does
not match the (previously) returned issue, there is a fair chance of a
user error.

Fixes: containers#1248
