cputest: Fix cpu-cpuid.py diff command

The cpuidMap in cpu-cpuid.py was created for converting old data files
(with QEMU's feature-words bits) to the new model-expansion based data.
When I added tests for CPU live update based on disabled/enabled feature
lists I shamelessly used the existing cpuidMap for generating the
*-{enabled,disabled}.xml data files. Thus any new CPUID bits which are
not present in the original cpuidMap would be ignored. The correct thing
to do is to use cpu_map.xml.

All data files were fixed by running the following command:

    ./cpu-cpuid.py diff *.json
