init-install-efi: Implement UUID support
Using UUID in favor of device names is more reliable as
UUID names are persistent.
Device names can change as the order of adding device nodes
is arbitrary. This sometimes results in device names switching
on each boot, which can cause system fail to boot.
Persistent naming solves these issues.
Used partition UUID in kernel command line to specify root partition.
Used partition UUID in /etc/fstab to specify swap partition.
Used filesystem UUID in /etc/fstab to specify boot partition.
