    CI: Discard stdout of cpplint
    
    It turns out that mixing stderr and stdout of cpplint is not a good idea
    as it will occasionally intermix "Done processing foo.cpp" lines on
    stdout, with linter error lines on stderr. When one such linter error is
    eliminated, the stdout line will be intermixed with a different stderr
    line, causing a spurious "new" error to appear.
    
    We redirect stdout to /dev/null to just avoid the "Done processing" and
    "Total errors found" lines altogether.
