refactor(tvix/glue/known_paths): drop some unused stuff r/7381
This are leftovers from the "reference scanning" approach (which we
didn't end up using).
We still want a concept of known paths, so we can trace IO into
storepaths back to the build recipe that'll produce it, so let's keep
the rest of this struct around.
