httppeer: move requestbuilder defaults into makepeer() argument

Upcoming commits will move the initial ?cmd=capabilities handshake
request out of httppeer so the handshake can be performed before a
peer instance is constructed. In order to do this, we'll need to
refactor code for making HTTP requests.

The type used to construct HTTP requests is configurable. If we'll
be making HTTP requests outside of httppeer, we should be able to
use a custom request builder. So move the definition of that type
into makepeer().

Extensions can monkeypatch the function and override the argument
value.
