Add script to generate fuzzer seed corpus from tests

This adds a script which runs the end2end_tests, captures a wire trace,
and then minimizes the corpus with the fuzzer. Minimizing the corpus
requires libfuzzer, so this only works in a Chromium checkout.

Unseeded, the fuzzer starts with coverage of about 600 features.
Using a seed corpus captured from the tests, the fuzzer quickly
increases coverage to about 10,000 features.
