This patch adds latest symlinks to the curiOS containers to make system
upgrades easier. I.e., a user can now reference the bundled image with:
set image oci-archive:/lib/oci/curios-httpd-latest.tar.gz
So that when they upgrade to the latest Infix, which might include an
update of curiOS httpd, they will get a seamless upgrade also of the
container(s) running.
