Convert overflow unit tests to KUnit, for better integration into the
kernel self test framework. Includes a rename of test_overflow.c to
overflow_kunit.c, and CONFIG_TEST_OVERFLOW to CONFIG_OVERFLOW_KUNIT_TEST.

$ ./tools/testing/kunit/kunit.py run overflow
JFYI, you can run this as a one-liner via
$ ./tools/testing/kunit/kunit.py run --kunitconfig /dev/stdin <<EOF
CONFIG_KUNIT=y
CONFIG_TEST_OVERFLOW=y
EOF
The above is taken from my own duplicate version of this patch

Ah-ha! I thought I remembered this conversion being proposed before but
I totally failed to find it. Thank you! I'll compare/adjust this patch
and add you as Co-developed-by.
