  cgroupfs: rework cgroup2 mounting

We now explicitly refuse to mount cgroups on pure unified layouts when the
container is not running in a separate cgroup namespace. This is not a
regression since we simply always failed before anyway. I will likely fix this
very soon though. But there are bigger fish to fry currently.
