The function are defined in the test_ubsan.c file, but not called
elsewhere, so delete the unused function.
lib/test_ubsan.c:137:28: warning: unused variable 'skip_ubsan_array'.
Reported-by: Abaci Robot <abaci@linux.alibaba.com>
Closes: https://bugzilla.openanolis.cn/show_bug.cgi?id=8541

But then I'll get warnings about test_ubsan_divrem_overflow() being
defined and not used. :)
