In some build environments Docker is already installed - and adding
podman is not an option. Add a new variable to toggle this, and
rename the now incorrectly titled DIB_CONTAINERFILE_PODMAN_ROOT to
just ...RUNTIME_ROOT to match.

We need to update the base reference platform we perform the
functional tests on. Debian bullseye seems like the best choice -- it
is recent enough to last for a while, and will match the
nodepool-builder container environment.

This makes the container file element search the active element list
for `containerfiles/${DIB_RELEASE}` for building. This makes it easy
to write wrappers for ubuntu/fedora/etc. containerfile elements.

This is a base element which uses a containerfile (Dockerfile) to
build a container image, then the filesystem is extracted from that
image and forms the root of the dib image.
You can add as little or as much to the dockerfile as desired.
