Make CR and trailing whitespace errors.

The canned CR and trailing whitespace presubmit checks only emit
warnings, so no one pays any attention to them and they don't fail the
build. All trailing whitespace was removed recently, and it has already
returned. This makes these checks actual errors so they will fail the
presubmit check on the bots, so that they will actually be seen.
