Bug#18415 known problem when mysql-test-run.pl run ActiveState perl for windows

 - Select STDOUT as default handle after having cloned the child
 - Disable check for "$error eq $output" to ptoperly redirect $error 


mysql-test/lib/mtr_process.pl:
  Restore output to STDOUT after forking the child
  Since STDOUT is not redirected disable to check to see if $output
  is equal to $error so STDERR is properly opened to $error
