    x86/gen-cpuid: Fix Py2/3 compatibility
    
    There is a fencepost error on the sys.version_info check which will break on
    Python 3.0.  Reverse the logic to make py2 compatible with py3 (rather than
    py3 compatible with py2) which will be more natural to follow as py2 usage
    reduces.
