    x86: add upgrade support to diag.sh
    
    Similar to how this is done in the diag.sh found in the base-files
    package, we should blink our status LED (if we have one) during the
    upgrade process. This follows the same blink pattern as seen at
    ./package/base-files/files/etc/diag.sh#L36
