Add tips to clean source tree to build help message. When user run kunit.py after building another kernel for ARCH=foo, it is necessary to run 'make ARCH=foo mrproper' to remove all build artifacts generated during the build. In such cases, kunit build could fail.

Would be better instead to detect if the last build was not done by kunit.py and call "make mrproper" inside kunit.py?
