string: Convert helpers selftest to KUnit
Convert test-string_helpers.c to KUnit so it can be easily run with
everything else.
Failure reporting doesn't need to be open-coded in most places, for
example, forcing a failure in the expected output for upper/lower
testing looks like this:
[12:18:43] # test_upper_lower: EXPECTATION FAILED at lib/string_helpers_kunit.c:579
[12:18:43] Expected dst == strings_upper[i].out, but
[12:18:43] dst == "ABCDEFGH1234567890TEST"
[12:18:43] strings_upper[i].out == "ABCDEFGH1234567890TeST"
[12:18:43] [FAILED] test_upper_lower
Currently passes without problems:
$ ./tools/testing/kunit/kunit.py run string_helpers
...
