[PATCH v2 6/6] toaster: fire TaskArtifacts event

[Ed Bartosh <ed.bartosh@linux.intel.com>]

Fire TaskArtifact MetaData event for deployment tasks when task
either completed or skipped. Event contains full task id
(recipe+task) and list of deployment artifacts from sstate
manifest.

This should allow Toaster to always get notified about deployment
artifacts produced by the build.

[YOCTO #9869]
