cooker: record events on cooker exit

Bitbake collects all events in special event queue when called with -w option. However, it starts to write events to the eventlog only after BuildStarted event is received. In some cases this event is not received at all, e.g. when bitbake is run with --parse-only command line option.

It makes sense to write all collected events when CookerExit event received to make sure all events are written into the eventlog even if BuildStarted event is not fired.
