df: push back psbt to validate iff peer requests confirmed inputs

Browse Source 
`openchannel_init` takes a psbt, which we pipe over to dualopend
process.

If the peer requests that they'll only accept confirmed inputs, we need
to go validate those before we continue.

This wires up the harness for this (validation check yet tc)
