Defining a task called do_deploy in an image recipe causes the
license_image bbclass in OE-core to think the recipe is not an image
recipe, which causes errors with license information collection if you
have an image recipe which depends on an image recipe using this
bbclass.

To fix this, and to add support for caching the signed binaries, use a
single task, do_sign_images (and its setscene task). The implementation
is based on deploy.bbclass, so the sstate is responsible for installing
the signed binaries in ${DEPLOY_DIR_IMAGE}, but using a different name
so that license information collection still works as expected.
