8250889: Disable testing SendReceiveMaxSize with preferIPv4Stack=true on the old impl until JDK-8250886 is fixed
Summary: The `test java/net/DatagramSocket/SendReceiveMaxSize` is currently failing when run with `-Djdk.net.usePlainDatagramSocketImpl` and `-Djava.net.preferIPv4Stack=true`. This fix removes these run settings from the test until a more permanent solution can be found.
