Fix config only being found below the working dir

The glob used to find files to lint was also being used to walk up to
find configuration files.  Given a file layout like:

foo/
	.htmlhintrc
	bar/
		test.html

htmlhint would not pick up the configuration if foo/bar/ was the working
directory, however it would if foo/ was the working directory.

bin/htmlhint
