amidi: ignore not only Active Sensing but also Clock bytes

Active Sensing messages are sent by many devices in the background and
would only interfere with the actual messages that amidi is supposed to
capture.  Therefore, amidi ignores them by default.  However, there are
also devices that send Clock messages with the same problem, so it is
a better idea to filter them out, too.
