Abort on UBSAN errors

Previously, UBSAN errors might slip undetected (e.g. when 23678758 is in).

Look for x = -2147483648:

• clang:asan - https://gitlab.isc.org/isc-projects/bind9/-/jobs/2945224#L1029
• gcc:asan - https://gitlab.isc.org/isc-projects/bind9/-/jobs/2945225#L1036

The builtin system test, which uses failing named -V, passed, tho error reports are somewhere in the output (look for main.c in the output):

• system:clang:asan - https://gitlab.isc.org/isc-projects/bind9/-/jobs/2945230
• system:gcc:asan - https://gitlab.isc.org/isc-projects/bind9/-/jobs/2945229

---

Validation jobs show that named -V with undefined behavior fails the test:

• clang:asan - https://gitlab.isc.org/isc-projects/bind9/-/jobs/2945017
• gcc:asan - https://gitlab.isc.org/isc-projects/bind9/-/jobs/2945016
• system:clang:asan - https://gitlab.isc.org/isc-projects/bind9/-/jobs/2945053
• system:gcc:asan - https://gitlab.isc.org/isc-projects/bind9/-/jobs/2945052
