Fix CPU load reporting independent of scheduler used.
- Sample CPU usage data from kern.cp_times, this makes for a far more
accurate and scheduler independent algorithm.
- Rip out the process list scraping that is no longer required.
- Don't update CPU usage sampling on every request, but every 15s
instead. This makes it impossible for an attacker to hide the CPU load
by triggering 4 samplings in short succession when the system is idle.
- After reaching the steady-state, the system will always report the
average CPU load of the last 60 sampled seconds.
