port number can be different from 3306 when doing the release builds
   with Do-compile, therefore it has to be replaced with the correct
   value during the test run using the "--replace_result" function.


mysql-test/r/rpl_error_ignored_table.result:
   - replaced hard-coded master port number with MASTER_PORT variable, since
     the port number is different when running the test suite during the 
     release builds with "Do-compile".
mysql-test/t/rpl_error_ignored_table.test:
   - replaced hard-coded master port number with MASTER_PORT variable, since
     the port number is different when running the test suite during the 
     release builds with "Do-compile".
