Via the docker-compose runtime test, we can exercise the full suite of
the docker-related packages: docker-compose, of course, but also
docker-engine, which in turn allows exercising containerd. The latter
by defualt uses runc as the container runtime, but can alternatively use
crun.
Extend the docker-compose runtime test with a variant that enables crun.
