rdbms: avoid "SHOW MASTER/SLAVE STATUS" queries in the GTID case

The binlog file/pos where only being used in __toString() for the GTID
case. Make that method use the GTID set instead and avoid querying the
old-fashioned binlog fields all together in that case. The STATUS
queries involve some global lock contention.
