* bpo-46913: Fix test_faulthandler.test_sigfpe() on UBSAN (GH-31662)
Disable undefined behavior sanitizer (UBSAN) on

* bpo-46913: Fix test_faulthandler.test_read_null() on UBSan (GH31672)
Disable undefined behavior sanitizer (UBSan) on
faulthandler._read_null().

* bpo-46913: test_hashlib skips _sha3 tests on UBSan (GH-31673)
If Python is built with UBSan, test_hashlib skips tests on the _sha3
extension which currently has undefined behaviors.
This change allows to run test_hashlib to check for new UBSan regression,
but the known _sha3 undefined behavior must be fixed.
(cherry picked from commit 6d0d7d2b8c1e04fd51c6cb29cc09a41b60b97b7b)
* bpo-46913: Skip test_ctypes.test_shorts() on UBSan (GH-31674)
If Python is built with UBSan, test_ctypes now skips test_shorts().
This change allows to run test_ctypes to check for new UBSan regression,
but the known test_shorts() undefined behavior must be fixed.
