Merge bitcoin/bitcoin#29667: fuzz: actually test garbage >64b in p2p transport test

626f8e398e fuzz: actually test garbage >64b in p2p transport test (Pieter Wuille)

Pull request description:

  This fixes an oversight from #28196: in the `p2p_transport_bidirectional_v2` fuzz test, when the desired garbage length is over 64 bytes, the code would actually use garbage length 0. Fix this.
