build-stx-images.sh: new parameter --os-label

New parameter --os-label allows one to tag & push images with the
specified label in place of the (default) OS id, eg:

  --os=distroless : look for "distroless" build recipes and tag
  them as "distroless"

  --os=distroless --os-label=debian : look for "distroless" build
  recipes, but tag them as "debian"

We need this in order to support both CentOS and Debian daily builds
generating and pushing distroless images to the same namespace in
Docker Hub, so that:

* CentOS jobs create distroless images with tags similar to
  master-distroless-stable-20220823T021745Z.0
* Debian jobs create distroless images with tags similar to
  master-debian-stable-20220823T021745Z.0
