CI: Run cpplint with --quiet
Instead of chopping the summary off the cpplint output, we can run it with --quiet. This causes the summary to be suppressed, but also messages such as "Done processing foo.cpp" which would cause the job to error out because of adding a line to the linter output if you added a new source file, for example. [skip cpplint] because some messages changed.
