Computes the lxmf.delivery destination hash for an Identity — the 16-byte
truncated SHA-256(name_hash("lxmf.delivery") ‖ identity_hash).
For a channel message this is the LXMF destination_hash the sender signs
over (the channel's delivery address), not the bare channel identity
hash. Confusing the two is the classic rfed bug — see RFed/SPEC.md
"CANONICAL WIRE FORMAT" invariants.
