bitbake: toasterui: listen for bb.event.MetadataEvent

The event mask for toasterui doesn't include MetadataEvents.
This means that we're missing the ArtifactFileSize event
(among others), which is the one we use to populate the SDK
artifact table.

Add that event type to the toasterui event mask so we can
record SDK artifacts as they are created.
