This is a request to update grub-probe and 10_linux to support the Linux
kernel's root=PARTUUID=... parameter.

Currently, grub-mkconfig passes the Linux kernel's device name in the root
parameter when booting a Linux system without an initramfs.  However, if the
devices get reordered then the system will fail to boot.  Current workarounds
for this is to either generate an initramfs that can mount the rootfs via
UUID, or to manually generate or update grub.cfg.

This patch updates grub-probe so that it can return the PARTUUID of MBR and
GPT volumes and enables 10_linux to pass the PARTUUID via the kernel's root
option.  This allows systems to automatically use PARTUUID (root=PARTUUID=...)
when an initramfs isn't present.

I have attached the a patch with the requested change and an example grub.cfg.
