refining tests as they appear to be non-deterministic.


mysql-test/suite/binlog/r/binlog_killed.result:
  results changed
mysql-test/suite/binlog/t/binlog_killed.test:
  restructuring the test to deliver more deterministic outcome.
  order-by for update and delete did not guaratee the order of scanning.
  --error are masked with zero in order to catch more info if killing
  really will happen to be non-deterministic on some platform (witnessed
  something like that on dl145j)
mysql-test/suite/binlog/t/binlog_killed_simulate.test:
  important guard added
