bitcoin/script: support for creating p2sh-p2wpkh.
...
We want this because P2SH is something we can tell bitcoind to pay to;
we can't (yet?) do that with "raw" P2WPKH.

bitcoin/script: helper to create ScriptCode for signing P2WPKH.
...
sign_tx_input() now takes a witness_script arg: P2WPKH doesn't really
have a witness_script, but for signing it behaves as if it does.
This helper constructs that "fake" witness_script.
