[SPARK-4008] Fix "kryo with fold" in KryoSerializerSuite
`zeroValue` will be serialized by `spark.closure.serializer` but
`spark.closure.serializer` only supports the default Java serializer. So it
must not be `ClassWithoutNoArgConstructor`, which can not be serialized by the
Java serializer.
This PR changed `zeroValue` to null and updated the test to make it work
correctly.
