Siddharth Shrimali 79f361aeb1 builtin/repack: actually drop filtered promisor blobs ...

Make --drop-filtered remove the enumerated promisor blobs instead of
only listing them.

The drop set is computed before repack_promisor_objects() runs, and on
a real run it is passed in so the rebuilt promisor pack omits those
blobs. --drop-filtered implies -d so the old promisor packs, which
still contain the dropped blobs, are removed. Without this the blobs
would survive in the redundant packs. The existing repack machinery
performs the write-before-delete and fsync, so the drop is crash-safe.

The dropped blobs become absent locally but remain recoverable from the
promisor remote, so a later access lazy-fetches them back
transparently. --dry-run keeps its previous behavior, i.e. it lists the
candidates and changes nothing.
