This is one of just 3 remaining "Test Module" kselftests (the others
being bitmap and printf), the rest having been converted to KUnit. In
addition to the enclosed patch, please consider this an RFC on the
removal of the "Test Module" kselftest machinery.

I tested this using:

$ tools/testing/kunit/kunit.py run --arch arm64 --make_options LLVM=1 scanf
