Remove "arbitrary named hierarchies" from the list of things that
cg_kernel_controllers() might return, and clarify that "name="
pseudo-controllers are not included in the returned list.
/proc/cgroups does not contain "name=" pseudo-controllers, and
cg_kernel_controllers() makes no effort to enumerate them via a different
mechanism.
