Add the gnu_printf (__printf()) attribute to the kunit_fail_current_test() implementation in __kunit_fail_current_test_impl(). While it's not actually useful here, as this function is never called directly, it nevertheless was triggering -Wsuggest-attribute=format warnings, so we should add it to reduce the noise.
