PRESUBMIT: Skip TODO(crbug.com/ pattern for upload warning

This CL admits the TODO(crbug.com/...) format for bug
references in the code base and avoids the presubmit
warning in those cases. This pattern is pervasive and
even necessary in some folders (e.g. ios/) so, although
it isn't linkified by cs.chromium.org, it's accepted.
