903f3d06275312aa4000b765d2287339210c61c1 fuzz: Check for addrv1 compatibility before using addrv1 serializer (practicalswift)

Pull request description:

  Fuzz addrv2 address serialization.

  Check for addrv1 compatibility before using addrv1 serializer.

  Before this

  ```
  $ src/test/fuzz/netaddr_deserialize
  netaddr_deserialize: test/fuzz/deserialize.cpp:84: void
      (anonymous namespace)::AssertEqualAfterSerializeDeserialize(const T &) [T = CNetAddr]:
      Assertion `Deserialize<T>(Serialize(obj)) == obj' failed.
  ```

  After this patch:

  ```
  $ src/test/fuzz/netaddr_deserialize
  …
  ```
