cpplint: Should use more up-to-date fork, not from styleguide

[EricCousineau-TRI]

Per this issue: google/styleguide#408

Consider the fork at https://github.com/cpplint/cpplint (also published to Pypi) if you feel like contributing.

Don't think I agree. We already fork ourselves, so it is not buying us anything.

[EricCousineau-TRI]

Yes, it may have additional overhead of configurations changing, but it may have improvements codewise that we may want at some point.

I'd call this closeable if we at least put a comment at the top of our forked cpplint pointing to the new stuff.

Sounds a little strange. I don't we should be deviating too much anyway unless the Google version is broken, whether to not there are improvements.

[EricCousineau-TRI]

Aye. Will close then.
