Add layer awareness to mirror-check.sh

This tool was missed when layered builds were introduced.
It looks for lst files under the wrong path. I've added
a layer arguement and fixed the path.

It also needs to ignore commented lines within lst files.

I also add dnf support.  Cloned from pkg-manager-utils.sh
since stx-tools is sometimes expected to stand on it's own.

One gap that I'm not addressing in this update.  It only
looks at the upstream repo, never at the cengn mirror.
If a package has been dropped by upstream, it reports as
missing.
