Add a simple unittest framework for create-diff-object implemented in
GNU Make.
It will automatically scan the kpatch-unit-objs/$(uname -m) directory
for specifically named files running one of 3 tests:
- creating diff object with expected success
- creating diff object with expected failure
- creating diff object and running a shell script on it with expected
success
