Change signatures to DerivedArtifact, and get Labels from non-Artifact sources when possible.

In tests, try to get artifacts directly from the actual configured target, rather than creating fresh ones.

This change should be a prod functional no-op, just changing signatures. Split out from the follow-up to reduce the diff.
