upload-pack: share more code 

We mark the objects pointed at our refs with "OUR_REF" flag in two
functions (mark_our_ref() and send_ref()), but we can just use the
former as a helper for the latter.

Update the way mark_our_ref() prepares in-core object to use
lookup_unknown_object() to delay reading the actual object data,
just like we did in 435c833 (upload-pack: use peel_ref for ref
advertisements, 2012-10-04).
