Subject: run complex image names with short names

In cases where the image name is more complex like:

quay/baude/alpine_nginx:latest  and is not from the docker
registry, we need to be able to run the image by its shortname
such as baude/alpine_nginx.  The same goes when the image is
not from a registry but instead has the localhost repository.

This resolves buildah issue #1034
