kunit: Add printf attribute to fail_current_test_impl
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.
Fixes: cc3ed2fe5c93 ("kunit: Add "hooks" to call into KUnit when it's built as a module")
