In its current form the test doesn't take into account the specification of `DatagramSocket.receive()` when a virtual thread is doing the `receive()`. There's already the `test/jdk/java/net/vthread/BlockingSocketOps.java` test which exercises the `receive()` through a virtual thread and verifies its specified behaviour, so we can skip this `InterruptibleDatagramSocket` test when a virtual thread is involved.
