9ab62d71fb1a54430ff5071bdb1120a414061288 [fuzz] Actually use mocked mempool in tx_pool target (dergoegge)

Pull request description:

  The current tx_pool target uses the default mempool, making the target non-deterministic. This PR replaces the active chainstate's mempool (i.e. the node's default mempool) with the already present mocked mempool in the target.
