Revert of PictureBenchmark JSON logging (https://codereview.chromium.org/286903025/)

Reason for revert:
Broke some Windows builds; see http://skbug.com/2609 ('certain Windows Build-* bots failing since r14905').

Before re-landing with a fix, please send to some of the trybots that failed the first time.

Original issue's description:
> Add JSON logging support to bench_pictures by adding a PictureResultsWriter class (in tools/PictureResultsWriter.h) to process logging information, using a very similar style as bench/ResultsWriter.h
>
> JSON format described in code, above PictureJSONResultsWriter class
>
