[OE-core] [wic][PATCH] mkefidisk.wks: use partition UUID and GPT partition table

[Ed Bartosh]

This is a preparation to use mkefidisk as a default wks for
genericx86* BSPs. This change enables usage of partition UUID
instead of device name to specify root partition in kernel
command line. It should make images to boot on devices with
boot device names that differ from what's mentioned in wks file.
