Added innodb_rollback_on_timeout option to restore the 4.1

InnoDB timeout behavior (Bug #24200)


mysql-test/t/innodb_mysql-master.opt:
  Set --innodb-lock-wait-timeout=2, since test for bug #24200 times out.
  
  This *could* cause random test failures if some long-running transaction concurrency is being tested.  However, such a test really should go in innodb-big or some other test file.
