Fix crash introduced by incorrect backport 806555e300. Commit 7f007e4a04 in master depends on 1476028225, but the latter was not backported. Therefore 806555e300 (the backport of commit 7f007e4a04) incorrectly used pg_strfold() in a locale where ctype_is_c.
The fix is to simply have the callers check for ctype_is_c. Because 7f007e4a04 was only backported to version 18, and because the commit in master is fine, this fix only exists in version 18.
