Subject: [PATCH v2 0/2] printf: convert self-test to KUnit

This is one of just 3 remaining "Test Module" kselftests (the others
being bitmap and scanf), the rest having been converted to KUnit.

I tested this using:

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

I have also sent out a series converting scanf[0].
