Cover letter [PATCH 0/2] Update kunit doc and tool with tips to build errors

kunit kernel build could fail if there are ny build artifacts from a prior kernel build. These can be hard to debug if the build artifact happens to be generated header file. It took me a while to debug kunit build fail on ARCH=x86_64 in a tree which had a generated header file arch/x86/realmode/rm/pasyms.h

make ARCH=um mrproper will not clean the tree. It is necessary to run make ARCH=x86_64 mrproper

Example work-flow that could lead to this:

        make allmodconfig (x86_64)
        make
        ./tools/testing/kunit/kunit.py run

Add this to the documentation and kunit.py build help message.
