packed_object_info(): use object_id for returning delta base
If a caller sets the object_info.delta_base_sha1 to a non-NULL pointer, we'll write the oid of the object's delta base to it. But we can increase our type safety by switching this to a real object_id struct. All of our callers are just pointing into the hash member of an object_id anyway, so there's no inconvenience. Note that we do still keep it as a pointer-to-struct, because the NULL sentinel value tells us whether the caller is even interested in the information.
