[OE-core] [PATCH 2/2] image-vm: Change default ROOT_VM to use PARTUUID

[Tom Rini]

From: Matt Porter <mporter at konsulko.com>

Support for finding the root partition via PARTUUID is a portable method to
determine the system root device as it does not depend on device ordering and
also abstracts the diference between IDE devices and SCSI/SATA/etc type
devices.
