Update compose files and makefile

Just some stuff that will probably need to be reverted before merge. Includes

- build custom user federation test dependency in container instead of requiring local java build.
- make container images use docker.io registry explicitly, for clarity.
- include environment variable for container runtime, defaulting to docker for backward compatibility.

The last two points ensure that podman can be used instead of docker.
