Unnecessary docker cleanup deletes the image you've just built

[regularfry]

I don't think this line is right:

repository-template/scripts/docker/docker.lib.sh

Line 55 in 5a9f3f2

docker rmi --force "$(docker images | grep "<none>" | awk '{print $3}')" 2> /dev/null ||:

It looks like an attempt to clean up intermediate images. However, when I run it on podman on a fairly ordinary dockerfile, I don't get any <none> images. That means the rmi command looks like this:

docker rmi --force ''

That has the effect of deleting everything, including the image that's just been built.

I don't think we need that cleanup line, but I'm open to suggestions otherwise.
