github/workflows: add support for testing different cgroup setups

Add support to run the Github workflow on three parallel runners, each
of them have a unique cgroup setup:
cgroup v1 only (legacy), cgroup v1/v2 (hybrid), cgroup v2 only (unified).

With this change, we should be able to run every patch against all
combination of cgroup setups.
