vendor in containers/(common,buildah,storage,image)

Changes as of 2022-04-21:

- apply-podman-deltas: minor cleanup
- buildah-tests.diff: deal with:
  . buildah #3894 (the registry one), which affected helpers.bash in
    a way that resulted in conflicts here; and
  . buildah #3917 (etchosts), which caused offset-only diffs
    with no conflicts
- Reevaluate the bud skip list, and reenable some tests that
  seems to be passing now under podman:
  . bud with specified context ...
  . two tests that require a local registry (which buildah now runs)
  . bud with --cgroup-parent
