Store raw json with run results when running safetynet_job.py.

Storing the machine-readable data is a good idea in general, in this
case allowing us to create graphs with the historical runs.

The json now also contains:
- a version number in case there are future changes in the format
- the date and time when the run started
- which profiler was used
- which commits were being compared
- whether a comparison was run or not, that is, if the commit hashes
  for before and after differ
