The candidate check of the meta index must use the proper suffix matching algorithm of the type system rather than plain suffix matching on a flat qualified record field's name in order to avoid false positive candidate partitions. E.g., the field extractor "ts" resolved to partitions that contained layouts with a field names "orig_pkts" rather than just those that only contained a field exactly named "ts". This change fixes that behavior.

@tobim please verify that this fixes the issue you've described. The check itself is rather simple.
This does not need a changelog entry since it should only be a speed improvement for some queries, but does not change any behavior in a user-facing way.
