[PATCH 0/2] repack: make `collect_pack_filenames()` consistent

[Taylor Blau <me@ttaylorr.com>]

This series combines a patch that Stolee wrote[1] as an RFC, along with
one that I added as a follow-up on top[2].

The details are spelled out in the commit messages, but the gist is that
the first patch restores behavior from prior to 73320e49ad
(builtin/repack.c: only collect fully-formed packs, 2023-06-07).

The second patch does not change any behavior, but reimplements
`collect_pack_filenames()` in terms of `get_all_packs()`, to make `git
repack`'s notion of which packs exist in a usable state in the
repository is consistent with `add_packed_git()`,
`install_packed_git()`, etc.
