open-channel: use pubkey, not arbitrary script for final outout address.
We need to pay to this from two places: on their side, it's a simple
payment, on our side, it's a complex timeout-or-mutual-or-hval script,
which doesn't lend itself to arbitrary scripts.
Use P2SH, of course.

check-anchor-scriptsigs: don't require txs.
It's convenient to double-check that commit txs spend anchor, but it's
misleading since we wouldn't have access to the other side's tx, and
in practice we wouldn't even sign ours until we need it.
