cpuacct: don't actually do anything.
All the information we have that is needed for cpuusage (and
cpuusage_percpu) is present in schedstats. It is already recorded
in a sane hierarchical way.
If we have CONFIG_SCHEDSTATS, we don't really need to do any extra
work. All former functions become empty inlines.
