buildstats-summary: add eventmask

Add eventmask 'bb.event.BuildCompleted' for buildstats_summary handler to avoid
running the codes in the handler everytime there's an event.

The codes in buildstats_summary only need to run for bb.event.BuildCompleted.
So add this event mask.

Also, we remove the redundant isinstance() statement in the handler.
