image.bbclass: Put image_complete under sstate control

Adding image_complete task should make sstate machinery
to generate manifest for deployed images and do final
deployment to DEPLOY_DIR_IMAGE.

Made sure IMGDEPLOYDIR doesn't contain images from past deployments
to prevent them to be included into sstate manifests.

Set stamp-extra-info flag for do_image_complete task. This flag
is used in the name of sstate manifest. Setting it to predetermined
value for image_complete should help to get correct manifest
filenames when processing runQueueTask events.
