[hotfix][connectors] Fix log format strings
Log4j uses '{}' instead of '%s' for interpolating values, meaning these
logging statements currently result in log entries with the literal string '%s'
instead of a useful value.
I ran into the one in `FlinkKafkaProducer011.java`, but did a brief search
in the `flink-connectors` module and found the others.
