do_deploy already has the to_build dependency
Without this, do_genimage will always be triggered.
This change is similar to oe-core's f61bcae0 ("image: Drop before
do_build from do_rootfs and do_image") which fixes the same issue for
the image class.

The artifacts created would be quite large and keeping multiple of them will consume a notable amount of disk space while the expected speed-up is really minimal. (For the same reasons, the image class does not generate sstate artifacts). Having SSTATE artifacts enabled here before also led to unexpected/unwanted behavior where a rootfs image recipe was rebuild and the binary output (file system image) changed but did not make it into the final genimage-generated disk image. This becomes a major problem, e.g. in the context of verified boot. Signed-off-by: Enrico Jörns <ejo@pengutronix.de>
