WebglConformance_conformance2_textures_image_bitmap_from_blob_tex_2d_rg32f_rg_float flakiness sighting

Project Member Reported by kbr@chromium.org, Dec 18 2017

Issue description

Flake seen here:
https://ci.chromium.org/buildbot/tryserver.chromium.mac/mac_optional_gpu_tests_rel/19075

from this V8 roll:
https://chromium-review.googlesource.com/c/chromium/src/+/832006

The test timed out. No crash of any Chrome sub-process was found.

Looking at the test, it seems there is a race condition where the onload handler for the XMLHttpRequest is being set after the request is sent. It should be being set before.

Attempt to fix WebGL roll script.

Fix footer generation by pulling logic from roll_webrtc.py. Should
eliminate duplicate specification of trybots.
