Rusty Russell ccff3ac437 lightningd/funding_tx: fill in scriptsigs for p2sh UTXOs.
This is a bit tricky: for our signing code, we don't want scriptsigs,
but to calculate the txid, we need them.  For most transactions in lightning,
they're pure segwit so it doesn't matter, but funding transactions can
have P2SH-wrapped P2WPKH inputs.
