ruby: convert global statistical variables to local ones.

Several statistical quantities collected by ruby where recorded / published
using global variables.  Since we want to have multiple ruby systems working
together, this is a hindrance.  Hence, we are convert such global variables to
local ones.

The src/python/m5/stats/__init__.py is being updated so that we go over ruby
stats and collate them as required.  It seems to me that we should have a
general way in which we can tailor the stats in python just before they are
sent to output.
