tweak Dockerfile so image is buildable with podman (#907)

This adds a docker.io registry name, the lack of which will otherwise
cause image building to fail if podman is used rather than docker.
Common images like node are automatically aliased and don't need
the registry name. Based on a problem reported in discord.
