Merge bitcoin/bitcoin#33429: fuzz: reduce iterations in slow targets

Browse Source 
6a33970fef fuzz: Reduce iterations in slow targets (marcofleon)

Pull request description:

  The `mini_miner`, `txdownloadman`, `txdownloadman_impl`, and `tx_pool_standard` fuzz targets are all slow-running targets. Fix this by reducing the iteration count in the `LIMITED_WHILE` loops.

  This should help decrease the run time of the fuzz CI jobs. See https://github.com/bitcoin/bitcoin/pull/33425.

  Addresses https://github.com/bitcoin/bitcoin/issues/32870 as well.
