genimage.bbclass: Add explicit error when used in a rootfs image

In contrast to wic, the genimage.bbclass is meant to be used from a separate recipe and should thus not be inherited from a rootfs image recipe. A proper check for this is to verify whether the 'image' class is inherited and abort parsing with an explicit error message. Signed-off-by: Enrico Jörns <[email protected]>
