tools: fix cpplint --quiet option

Currently, the --quiet option for cpplint will generate the following
error:
$ tools/cpplint.py  --quiet src/node.cc
Traceback (most recent call last):
  File "tools/cpplint.py", line 6529, in <module>
    main()
  File "tools/cpplint.py", line 6497, in main
    filenames = ParseArguments(sys.argv[1:])
  File "tools/cpplint.py", line 6437, in ParseArguments
    logger.addHandler(logging.FileHandler(val, mode='wb'))
  File "/python2.7/logging/__init__.py", line 911, in __init__
    StreamHandler.__init__(self, self._open())
  File "/python2.7/logging/__init__.py", line 941, in _open
    stream = open(self.baseFilename, self.mode)
IOError: [Errno 21] Is a directory: '/Users/danielbevenius/work/nodejs/node

This commit moves the FileHandler that currently exists in the quiet
option to the logfile clause. It looks like this issue came about when
merging in commit fee4d3a ("tools:
merge custom cpplint with cpplint v1.3.0").
