MariaRocks port: fix tests

- rocksdb.tmpdir works (however @@rocksdb_tmpdir has no effect yet!)
- trx_info_rpl is only run in RBR mode
- type_char_indexes_collation now works
  = take into account that characters with the same weight can have
    any order after sorting (and they do in MariaDB)
  = MariaDB doesn't use index-only for extended keys that have partially-
    covered columns.
