verify-hashed-objects: add `jio verify hashed-objects`

This is currently very hacky and unfinished, but does enough for
some performance comparisons against a zstd-using journalctl --verify
that has been hacked to return early after the first pass.

It's currently rather leaky, the whole per-object-dispatch thingy
is illuminating a thunk_h shortcoming and forcing addressing the
issue... soon.
