4a2d051285 minor is_cpu_vulnerable() changes (#71) 
* correct is_cpu_vulnerable() comment

As far as I can tell, the function and usage are correct for the comment
to be inverted.

Add a clarifying note as to why the value choice makes sense.

* exit on invalid varient

If this happens, it's a bug in the script. None of the calling code
checks for status 255, so don't let a scripting bug cause a false
negative.

* no need to set vulnerable CPUs

According to comment above this code:
'by default, everything is vulnerable, we work in a "whitelist" logic here.'

bc4e39038a fix(opcodes): fix regression introduced in previous commit 
We were saying unknown instead of vulnerable when the count of lfence opcodes was low
This was not impacting batch mode or the final decision, just the human-readable output of the script.

52a8f78885 send warning to stderr. (#53) 
With --batch json there must not be any other output on stdout, so redirect warnings to stderr will show the warning on the console and only the json output is on stdout.
