channeld: BOLT update, no longer allow creation of old (experimental-only!) non-zero-fee anchor channels.

These were removed from the spec.

We still support existing ones, though we were the only implementation
which ever did, and only in experimental mode, so we should be able to
upgrade them and avoid a forced close, with a bit of engineering...
