test: Use feerate higher than minrelay fee in wallet_fundraw

The external input weight test in wallet_fundrawtransaction.py made
transactions at the minimum relay fee. However due to ECDSA sometimes
making a shorter signature than expected, the size estimate (and
therefore the funded fee) ends up being a little bit too low, which
results in the final transaction being under the min relay fee. We can
compensate for this by just using a feerate higher than the minrelayfee
as the actual feerate itself does not matter in this test.
