[PATCH] lib/bb/event: improve handling of event queue on exit

[Paul Eggleton <paul.eggleton@linux.intel.com>]

If BitBake exits before a UI handler (server) has been registered, we
print the event queue; if there are any errors or other non-debug
messages just print these and suppress the rest of the message queue.

This improves the output when sanity check failures occur with OE-Core
by avoiding printing a long stream of uninformative debug messages.
