Fix tests when InnoDB is not built-in. Innodb options would cause
mysqld to abort with an error indicating that the option is unknown.
Fix tests on Windows where mysql-test-run.pl was unable to probe
mysqld for version and variables information, caused by output
being redirected to a log file instead.

  output sent to the console. This fixes help output on Windows
  because it enables this option by default.
