Very small fixes for testsuite (a real_sleep instead of sleep, plus TCP port independency of the result file).


mysql-test/r/rpl_server_id1.result:
  be port-independent
mysql-test/r/rpl_server_id2.result:
  be port-independent
mysql-test/t/rpl_error_ignored_table.test:
  we want to sleep 2 secs, not more; if we allow ourselves to sleep >=10 seconds, then
  the get_lock() will be aborted and we will arrive to late for the KILL to have
  the desired effect of generating an error code in the binlog.
