lib: overflow: Convert to Kunit

Browse source 
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
