[PATCH] runqueue: Handle BBHandledException correctly

[Richard Purdie <richard.purdie@linuxfoundation.org>]

If we see a BBHandledException in runqueue, the understanding is the system
handled it, printing a log and traceback is just confusing.

Therefore only print these in the cases where its an unknown/unhandled
exception.
