4185a86d90 df-mfc: set the minimum input weight to 110 iif v2

b01734087d df-mfc: set protocol type when we know it 
We'll use it for figuring out whether or not to set a utxo witness
minimum, which comes much before we were setting this field.

Now we set the protocol as soon as we can reasonably deduce it.

e81d78ec4c fundpsbt/utxopsbt: new min_witness_weight param 
Needed for v2 of channel opens, where the minimum weight is 110; a
'simple utxo' (sig + key) weighs in at 107, so we a need a way to
establish a floor for this case.

Changelog-Added: JSON-RPC: fundpsbt/utxopsbt have new param, `min_witness_utxo`, which sets a floor for the weight calculation of an added input
