  cgroups: ignore cgroup2 limits on non-cgroup2 layouts

Mixing cgroup2 and legacy cgroup systems such that some controllers are enabled
in legacy cgroup hierarchies and other controllers in the unified hierarchies
is simply not something we're supporting. Even systemd's hybrid layout (crazy)
doesn't bind controllers to the unified cgroup hierarchy.
