Subject: [PATCH] kunit: add --make_options

The kunit.py utility builds an ARCH=um kernel and then runs it. Add
optional --make_options flag to kunit.py allowing for the operator to
specify extra build options.

This allows use of the clang compiler for kunit:
tools/testing/kunit/kunit.py run --defconfig \
--make_options CC=clang --make_options HOSTCC=clang

Nice! This worked for me with all of the options I tried (and it's
great to see KUnit working on clang builds!)

Please rebase on Linux 5.6-rc5 and resend. I tried applying
on Linux 5.6-rc1 as well as 5.6-rc5 and both fail.
