cgroup: also include "cgroups.threads" in the list of files to chown

Also, add "cgroups.stat". It's read-only anyway, hence its UID/GID
ownership matters little, but it's probably a good idea to keep it
ownership in sync with the other read-only files such as
"cgroups.controllers".

Also, order the list of files alphabetically.
