Subject: [PATCH] Simplify whitespace-linter script

Pegleg currently uses `find` to search files in the whitespace-linter
script. A more simplified approach could be taken by using `git grep`
instead. This method levarages .gitignore so a separate list of files
in the script no longer needs to be maintained. This is the method used
by Airship Armada.
