    imx6: bootscript-apalis: make it working on v2021.01 release
    
    Upstream in commit 8b9c0cb46471 ("apalis_imx6: boot env configuration
    updates") removed emmc legacy wrappers, but so far didn't included any
    replacements. Fix it by simply defining the missing variables and UUID
    gathering directly into the boot script.
