We don't have any tests that verify that git-pack-objects(1) works with
`--stdin-packs` when combined with alternate object directories. Add
some to make sure that the basic functionality works as expected.

When passing the same packfile both as included and excluded via the
`--stdin-packs` option, then we will return an error because the
excluded packfile cannot be found. This is because we will only set the
`util` pointer for the included packfile list if it was found, so that
we later die when we notice that it's in fact not set for the excluded
packfile list.
Fix this bug by always setting the `util` pointer for both the included
and excluded list entries.

When passed the same packfile twice via `--stdin-packs` we return an
error that the packfile supposedly was not found. This is because when
reading packs into the list of included or excluded packfiles, we will
happily re-add packfiles even if they are part of the lists already. And
while the list can now contain duplicates, we will only set the `util`
pointer of the first list entry to the `packed_git` structure. We notice
that at a later point when checking that all list entries have their
`util` pointer set and die with an error.
While this is kind of a nonsensical request, this scenario can be hit
when doing geometric repacks. When a repository is connected to an
alternate object directory and both have the exact same packfile then
both would get added to the geometric sequence. And when we then decide
to perform the repack, we will invoke git-pack-objects(1) with the same
packfile twice.
Fix this bug by removing any duplicates from both the included and
excluded packs.

The test suite for git-pack-objects(1) is quite huge, and we're about to
add more tests that relate to the `--stdin-packs` option. Split out all
tests related to this option into a standalone file so that it becomes
easier to test the feature in isolation.
