When index-pack completes a thin pack it appends objects to the pack.
Since the commit 92392b4(index-pack: Honor core.deltaBaseCacheLimit when
resolving deltas) such an object can be pruned in case of memory pressure.

To be able to re-read the object later, a few more fields have to be set.

Noticed by Pierre Habouzit.

    OK, I hope the comment is what was expected. My lack of knowledge
    made we wonder what to write... :-/

    Hm, we get the object via read_sha1_file, can that return a delta? I
    would not expect it to.  Sorry, never looked at those code paths
    (and don't have the time to investigate at the moment).
