Fix duplicate check - too unspecific

The check is too unspecific, it currently allows partial line matches.

This prevents broader entries to be added after more specific ones.

Example: after lancache.steamcontent.com is added, steamcontent.com will be wrongfully skipped.

This change will make sure only exact duplicates are skipped.
