This indirection does not add anything in terms of configuration and
only serves to increase confusion; and given the nature of these it is
unlikely they are being used outside of OE-Core. Change the sato-sdk and
sato-dev images to be based on the main Sato image (avoiding the need
for a common SATO_IMAGE_FEATURES variable) and eliminate all references
to them.
Fixes [YOCTO #2458].
