feat(util/match_against): report differences in both direction

When comparing two configs, or logs against a specific config, missing
dps and type mismatches were reported, but extra dps were not. To get
extra dps reported, you needed to run one of the other matching utilities.

Add reporting of extra dps so that one utility is enough to get a full picture
of compatibility.
