app/trace: emit owner descriptions 



Now that we have a real description for an event's owner, print those
descriptions instead of the old owner_type prefix + poller_id.

Note that we need to take the event's tsc into account, if it is older than
when the associated owner was registered we should not print the description
because it is for an owner that was unregistered after the event was
generated.
