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: set GIT_EXEC_PATH in guilt wrapper
+
+git has the habit of tracking the directory where it was 
+installed. If you build git, relocate git and then remove
+the old directory --exec-path will return that original
+(now non-existent) directory. We insist that git and 
+guilt be in the same directory to ensure they are matched,
+so we use the environment variable GIT_EXEC_PATH to 
+force the issue.
