Merge bitcoin/bitcoin#28952: fuzz: Avoid timeout in process_messages

Browse Source 
fa825975b57bc5c4323e5d6f4bc8cd2b8189e238 fuzz: Avoid timeout in process_messages (MarcoFalke)

Pull request description:

  Reduce the number of messages per fuzz input. There should be no reason to have more messages than that.

  This should also avoid timeouts, such as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=64548. CC https://github.com/bitcoin/bitcoin/issues/28812
