bbbb51877a fuzz: Speed up transaction fuzz target (MarcoFalke)

Pull request description:

  `hashBlock` and `include_addresses` are orthogonal, so no need to do an exhaustive "search".

  Might fix https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=34491

    cr ACK bbbb51877a: patch looks correct, and `TxToUniv` surprisingly wide in the `transaction_fuzz_target` flame graph! Putting it on a diet makes sense.
