[BUG]: /sys/fs/cgroup has no file in busybox image

[Ace-Tang]

Ⅰ. Issue Description

Running a container with pouch, and check ls /sys/fs/cgroup is null

ace@www:~/go/src/github.com/docker/docker  (v1.12.6) time-> 六 4月 28 00:12:17
$ sudo pouch run -it registry.hub.docker.com/library/busybox:1.28 sh
/ # ls /sys/fs/cgroup/
/ # exit
ace@www:~/go/src/github.com/docker/docker  (v1.12.6) time-> 六 4月 28 00:12:43
$ sudo pouch run -it reg.docker.alibaba-inc.com/base/busybox:latest sh
/ # ls /sys/fs/cgroup/
/ # 

while I run a container with moby, I found that ls /sys/fs/cgroup has files

ace@www:~/go/src/github.com/docker/docker  (v1.12.6) time-> 五 4月 27 23:21:45
$ docker run -d  reg.docker.alibaba-inc.com/base/busybox:latest top

I wonder that is images pulled by pouch and moby are different .
