For "make integration", the tests are run inside a Docker/Podman container. Problem is, if cgroup v2 is used, the in-container /sys/fs/cgroup/cgroup.subtree_control is empty. The added script, used as Docker entrypoint, moves the current process into a sub-cgroup, and then adds all controllers in top-level cgroup.subtree_control.
