Only CONSUMER.INFO was missing from a machine's grants; the rest was already there

Binding to a consumer asks the server about it and hears the answer on the
client's inbox; hearing a declaration acknowledges it. A machine's user was granted
none of that and was refused the first time one dialled a permissioned server:
"this node cannot read its declarations". Its inbox is its own prefix, which the
host now sets.
