hs_pow: Modify challenge format, include blinded HS id
This is a protocol breaking change that implements nickm's
changes to prop 327 to add an algorithm personalization string
and blinded HS id to the EquiX challenge string for our onion
service client puzzle.
This corresponds with the spec changes in torspec!130,
and it fixes a proposed vulnerability documented in
ticket tor#40789.
Clients and services prior to this patch will no longer
be compatible with the proposed "v1" proof-of-work protocol.
