Users can ask git-commit-graph(1) to write a commit graph specifically for a set of packfiles via the "--stdin-packs" option. Those users are expected to pass in relative paths, and those eventually get resolved in `fill_oids_from_packs()`. This ties the logic in "commit-graph.c" to the specific object database source, as the subsystem now needs to assume where a specific packfile is located relative to the source itself. Refactor the logic to instead require the caller to pass in resolved packfiles to untangle that dependency. This also makes the next change easier to implement, where we'll get rid of passing the source to the commit-graph subsystem.
