Fix lc_collate_is_c() when LC_COLLATE != LC_CTYPE. An unfortunate typo in commit 2d819a08a1 can cause wrong results when the default collation provider is libc, LC_CTYPE=C, and LC_COLLATE is a real locale. Users with this combination of settings must REINDEX all affected indexes.
The same typo can also cause performance degradation when LC_COLLATE=C and LC_CTYPE is a real locale. Problem does not exist in master (due to refactoring), so fix only in version 17.
