    uboot-envtools: Fix format of autogenerated sectors
    
    The sector number must be stored in hex. Otherwise, the number (like 16)
    will be parsed as hex and any write to the partition will end up with an
    error like:
    
      MTD erase error on /dev/mtd5: Invalid argument

    Fixes: 54b275c8ed3a ("ipq40xx: add target")
