bundle2: allow bundle2 for pulling over the wire

This changeset makes `wireprotocol` peers advertise bundle2 capability and
comply with bundle2 `getbundle` requests.

Note that advertising bundle2 could make a client try to use it for push. Such
pushes would fail. However, I do not expect any human being to have enabled
bundle2 on their server yet.
