I see that I can't just remove `!build_with_chromium`, because test_main uses
logging methods that are not implemented in Chromium's override.

So I just replaced that with `rtc_include_tests` which is technically equivalent
and seems like a workaround, but really it's how it's supposed to have been all
along; this is test code, after all.
