Fix directory pull image name for OCI images

Browse Source 
This is a breaking change and modifies the resulting image name when
pulling from an directory via `oci:...`.

Without this patch, the image names pulled via a local directory got
processed incorrectly, like this:

```
> podman pull oci:alpine
> podman images
REPOSITORY      TAG      IMAGE ID       CREATED       SIZE
localhost/oci   alpine   4fa153a82426   5 weeks ago   5.85 MB
```

We now use the same approach as in the corresponding [buildah fix][1] to
adapt the behavior for correct `localhost/` prefixing.

[1]: https://github.com/containers/buildah/pull/1800

After applying the patch the same OCI image pull looks like this:

```
> ./bin/podman pull oci:alpine
> podman images
REPOSITORY         TAG      IMAGE ID       CREATED       SIZE
localhost/alpine   latest   4fa153a82426   5 weeks ago   5.85 MB
```

End-to-end tests have been adapted as well to cover the added scenario.
