util/lint: Update license linter, make stable version

- Split the script up to make it easier to update and read.
- Check for multiple different license strings. Not all files are GPL
licensed.
- Don't validate 0 length files
- Update list of files to exclude from the license header check.
- Add command line option to set directories to check

- Add stable version to check a few directories that are fixed.  This
just calls the non-stable version with the directories to check.
