abstraction-map: Add (currently) unmappable cpu.stat

Add an unmappable mapping for the cpu.stat setting.  While
the filename, cpu.stat, maps perfectly from v1 <-> v2, the
contents do not.  At this time, let's set this as unmappable
and revisit it when we've thought through the best way to
map the contents.
