Merge bitcoin/bitcoin#21892: fuzz: Avoid excessively large min fee rate in tx_pool
99993f066405863c66ccaec0a8427129f4515768 fuzz: Avoid excessively large min fee rate in tx_pool (MarcoFalke)
Pull request description:
Any fee rate above 1 BTC / kvB is clearly nonsense, so no need to fuzz this.
Hopefully fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=34078
