Bug#32510 LIKE search fails with indexed 'eucjpms' and 'ujis' char column

Problem: some collation handlers called incorrect version
of my_like_range_xxx(), which led to wrong min_str and max_str,
so like range optimizer threw away good records.
Fix: changing the wrong handlers to call proper version of
my_like_range_xxx().
