Add or display ASAN_OPTIONS in crash report

[posidron]

Example: https://fuzzmanager.fuzzing.mozilla.org/crashmanager/crashes/3637015 (see Environment). Observation is based on the rr reports in which this is not included or displayed.

What exactly is missing? I can add this info to the crash report but FFPuppet manually updates ASAN_OPTIONS (https://github.com/MozillaSecurity/ffpuppet/blob/master/ffpuppet/helpers.py#L229) so it won't be accurate.

The used ASAN_OPTIONS for the individual run, similar to what we attach with the above LibFuzzer output. Dunno about the preferences here but for LibFuzzer it is just attached to the submit report to FM.

Maybe FFPuppet should print them at launch? Especially since it could be modifying them.
