grunt: Update grunt-contrib-jshint use built-in jshintrc parser

Use built-in jshintrc option for 'jshint' config instead of
parsing manually and strippig comments.

node-jshint itself has supported comment parsing for a long time
(which is why our Jenkins build, which doesn't even use grunt,
has no problem with our .jshintrc file).

But the grunt task never exposed this parser, until v0.6.4.
