pack-objects: allow `--filter` without `--stdout`

9535ce7337 (pack-objects: add list-objects filtering, 2017-11-21) taught `git pack-objects` to use `--filter`, but required the use of `--stdout` since a partial clone mechanism was not yet in place to handle missing objects. Since then, changes like 9e27beaa23 (promisor-remote: implement promisor_remote_get_direct(), 2019-06-25) and others added support to dynamically fetch objects that were missing. Even without a promisor remote, filtering out objects can also be useful if we can put the filtered out objects in a separate pack, and in this case it also makes sense for pack-objects to write the packfile directly to an actual file rather than on stdout. Remove the `--stdout` requirement when using `--filter`, so that in a follow-up commit, repack can pass `--filter` to pack-objects to omit certain objects from the resulting packfile.
