shutdown: don't allow shutdown to p2pkh or p2sh addresses for anchor outputs.

Browse Source 
This doesn't have an effect now (except in experimental mode), but it
will when we support anchors.  So we deprecate the use of those in the
close command too.

For experimental mode we have to avoid using p2pkh; adapt that test.

Changelog-Deprecated: JSON-RPC: `shutdown` no longer allows p2pkh or p2sh addresses.
