Akihiro Suda 42b1175eda hack/dind: fix cgroup v2 evacuation with docker run --init ...

Evacuate all the processes in `/sys/fs/cgroup/cgroup.procs`, not just PID 1.

Before:
```console
$ docker run --rm --privileged --init $(docker build -q .) cat /sys/fs/cgroup/cgroup.subtree_control
sed: couldn't flush stdout: Device or resource busy
```

After:
```console
$ docker run --rm --privileged --init $(docker build -q .) cat /sys/fs/cgroup/cgroup.subtree_control
cpuset cpu io memory hugetlb pids rdma
```

Fix docker-library/docker issue 308
