Create the cgroupfs mount point in sysfs.
Create the /sys/fs/cgroup directory when cgroups are available. This
creates the empty directory to serve as the mountpoint, actually
mounting cgroups is left to the launcher/userspace. This is consistent
with Linux behaviour.
Without this mountpoint, getdents(2) on /sys/fs indicates an empty
directory even if the launcher mounts cgroupfs at /sys/fs/cgroup. The
launcher can't create the mountpoint directory since sysfs doesn't
support mkdir.
