Should not fail on trying to serialize `java.time.DateTimeException`

Describe your Issue

(note: offshoot of FasterXML/jackson-modules-java8#319)

Looks like checks to support detection of "missing Java 8 date/time ser/deser support" gives false alert on DateTimeException. And since it should be serializable just fine (as opposed to value types where POJO handling would be wrong), we should relax check in BeanUtil to not block it.

But instead of allow-listing one name, I think we should just skip all Throwable types.
