cgroup: don't include sys/mount.h if not needed

As cgroup implementation only works on Linux, it does not
make much sense to include sys/mount.h if other requirements are
not met, such as HAVE_MNTENT_H and HAVE_GETMNTENT_R.

Also, it fixes build on OpenBSD that requires to include sys/param.h
along with sys/mount.h.
