pack-objects: split out `--stdin-packs` tests into separate file 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.

pack-objects: fix error when packing same pack twice 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.

tests: teach callers of test_i18ngrep to use test_grep They are equivalents and the former still exists, so as long as the only change this commit makes are to rewrite test_i18ngrep to test_grep, there won't be any new bug, even if there still are callers of test_i18ngrep remaining in the tree, or when merged to other topics that add new uses of test_i18ngrep.
