unnecessary copy of input image with --local

[cgwalters]

Today even when operating on the host container storage (the now expected default) we seem to do a copy of the input image into a temporary osbuild store. I'm trying to use bib more in my daily driver and the copy is noticeable vs what is done in e.g. https://github.com/containers/podman-bootc-cli where we just directly run the input container.

We're seeing use cases for people putting substantial amounts of data in container images, and the extra copy here is more problematic.

See osbuild/osbuild#1804 for the underlying issue.
