Title: Loadavg collector: use platform independent os.getloadavg() instead of /proc/loadavg

Mac OS X does not have `/proc/loadavg` to get the load averages from
python however provides platform the independent ```os.getloadavg()``` as equivalent.

Unfortunately, processes_running and processes_total are not available, so that still has to be done with /proc/loadavg
