google-breakpad: cherry-pick 875 from upstream

Note that this and the previous cherry-pick 830 should be reverted
before attempting to pull all the upstream changes.  While this
one patched without any issues, 830 did not fully patch due to
entire files that were missing.

BUG=chromium-os:21903
TEST=CrashSender/UserCrash autotests
