Carla Kirk-Cohen 014683ee66 routing: include route blinding fields in blinded portion of path ...

This commit updates route construction to backfill the fields
required for payment to blinded paths and set amount to forward
and expiry fields to zero for intermediate hops (as is instructed
in the route blinding specification).

We could attempt to do this in the first pass, but that loop
relies on fields like amount to forward and expiry to calculate
each hop backwards, so we keep it simple (stupid) and post
processes the blinded portion, since it's computationally cheap
and more readable.
