libcgroup doesn't really have an API for mounting things.

Note however, that when libcgroup initializes it figures out where the
hierarchies are mounted based on the mount info exported by the kernel,
so regardless who mounted the hiearchies and where they are mounted
libcgroup actually does the right thing.
