guilt: import guilt for kernel patch management

The Wind River kernel is "patched" via guilt to provide
both git integration and quilt like patch management
(if that is of interest).

This is a modified 0.33 guilt with some changes to
streamline interactions with the way that the Wind
River kernel is constructed. That being said, the
common semantics of guilt are not changed, and it
can be used for other purposes.

+guilt: allow operation outside of git repos
+
+Sometimes guilt is sourced when there isn't a containing git repository.
+Some of the git commands that are always called will report errors 
+unecesarility in this scenario. This adds a variable that will inhibit
+those problematic calls
