[PATCH 3/3] init-install-efi: fix script for gummiboot loader

[Saul Wold <sgw@linux.intel.com>]

From: "Ng, Mei Yeen" <mei.yeen.ng@intel.com>

After running gummiboot loader install option, the installed target
storage device boot parameter for root=PARTUUID is empty causing boot failure.
This issue is only observed with gummiboot and not with GRUB loader.

This fix assign the rootuuid of the rootfs partition for gummiboot loader.
