[PATCH v4 09/12] builtin/pack-objects: introduce obj_is_packed()

[Christian Couder <christian.couder@gmail.com>]

From: Jeff King <peff@peff.net>

Let's refactor the way we check if an object is packed by
introducing obj_is_packed(). This function is now a simple
wrapper around packlist_find(), but it will evolve in a
following commit.
