    Bug#20225524 TESTS SHOULD USE AT LEAST 60 SEC TIMEOUT FOR SHUTDOWN_SERVER
    COMMAND

    Removed timeouts less than the default from all shutdown_server commands in the
    .tets and .inc files

A proper fix would be to use include/restart_mysqld.inc etc, but let's take the upstream fix to reduce the diff.
