pinebookpro-uboot: fixed kernel.d script
https://github.com/void-linux/void-packages/pull/40128

Description:
The original (rev. 2) does not work e. g. with encrypted root and also fails if there are certain commented out lines in /etc/fstab. This proposed version fixes both issues. If the / line in fstab does not include UUID, the device is taken directly from fstab.
