operators_test invokes undefined behavior in random input tests about utility HOT 2 OPEN

Those tests are 20 years old. Since they are stable and don't seem to cause problems on any compiler (despite triggering UB), I'd say we keep them. Disabling them for UBSAN seems fine to me, but I don't feel that any more action is needed, especially given that there is no real development for Boost.Operators now that we have the spaceship operator.

This doesn't cause problems because we don't run the tests on hardware that e.g. triggers a hardware exception on overflow, and we don't use the results of the operators other than to test they are the same for Wrapped and the underlying type (i.e. that garbage equals garbage).

If there isn't a point to use random input, and run the tests a 1000 times to boot, I would rather replace these tests with a single set of tests with predefined data. Or remove the tests completely, if this is covered elsewhere. Testing UB is just wrong, anyway.
