Fix for mysql >=  5.5, TYPE=InnoDB no longer supported

We run MySQL 5.7 where as the default RHEL6 mysql is 5.1.
When creating the tables it on 5.7 it fails since  TYPE=InnoDB is deprecated in mysql 5 and dropped completly in 5.5.

This patch causes ENGINE=InnoDB to be used instead.

See http://bugs.mysql.com/bug.php?id=59288 for some background.

Not tested but should be okay for all MySQL 5 versions.
