    base-files: more robust sysupgrade on NAND
    
    Make sure sysupgrade on NAND also works in case of UBI volumes having
    index >9. While at it, also make sure UBI device is detected and abort
    in case it isn't. Use Shell built-in shorthand ':' instead of 'true'.
    
    Fixes #9708

    (cherry picked from commit 0dbca1b2baf9c26514b517a1e5860f6a5b04d5ae)
