[PATCH] cgroup: Fix indent for /proc/cgroups

Currently, /proc/cgroups outputs is fairly ugly as following,
#subsys_name hierarchy num_cgroups enabled
cpuset 0 1 1
debug 0 1 1
ns 0 1 1

indent it in a good-looking way.
#subsys_name hierarchy num_cgroups enabled
cpuset 0 1 1
debug 0 1 1
ns 0 1 1

But if there's a subsystem with name length >= 8,
it won't be aligned properly..
