If we're going to run this on the bots, we should at least be consistent about
it. Can you add entries to the main mac and linux bots as well?

The change to the win bots looks correct. You should be able to see that it
works in the try jobs.

Right, I forgot to mention in the commit message that the Linux and Max bots
already seem to be running these tests (there already are such gtest_tests
entries in chromium.{linux,mac}.json).
