Documentation: update cgroupfs mount point
According to commit 676db4af0430 ("cgroupfs: create /sys/fs/cgroup to mount cgroupfs on") the canonical mountpoint for the cgroup filesystem is /sys/fs/cgroup. Hence, this should be used in the documentation.

The constraint on the period is that a subgroup must have a smaller or
equal period to its parent. But realistically its not very useful _yet_
