[JENKINS-50124] restore AbstractTaskListeners serialVersionUID.

If a subclass was serialized (default java serialization) then the changes do push down the method to the interface would break deserialisation when in reality the classes are still compatable. Restoring the compatability by hard coding the serialVersionUID to what it was before the change. (cherry picked from commit dcf22ca)
