    image: define DEVICE_DTS_DELIMITER as per-device variable
    
    DEVICE_DTS_DELIMITER needs to be in the DEFAULT_DEVICE_VARS
    list to work as expected. This was missing from the original
    version and got overlooked.
    
    Fixes: fd6790864739 ("scripts: mkits.sh: Allow legacy @ mode for dts creation")
