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.

Nit: could perhaps that line be broken in a bit more readable way?
build_parser = subparser.add_parser('build',
help='Builds a kernel with KUnit tests. '
'Successful build depends on a clean source tree. '
'Run mrproper to clean generated artifacts for prior '
'ARCH=foo kernel build. '
'Run "make ARCH=foo mrproper"')
It improves readability. Will fix it.
(fixed "artifacts" while I was in the neighborhood :)
Thanks for catching it.
thanks,
