Refactor the sending of the "agent" and "object-format" capabilities into a function. This was added in its current form in ab67235bc4 (connect: parse v2 refs with correct hash algorithm, 2020-05-25). When we connect to a v2 server we need to know about its object-format, and it needs to know about ours. Since most things in connect.c and transport.c piggy-back on the eager getting of remote refs via the handshake() those commands can make use of the just-sent-over object-format by ls-refs. But I'm about to add a command that may come after ls-refs, and may not, but we need the server to know about our user-agent and object-format. So let's split this into a function.
