If no root= switch is specified on the kernel command line we'll use the root disk on which the partition the LoaderDevicePartUUID efi var is located – as long as that partition is an ESP. Let's slightly liberalize that and also allow it if that partition is an XBOOTLDR partition. This ensures that UKIs spawned directly from XBOOTLDR work the same as those from the ESP. (Note that this makes no difference if sd-boot is in the mix, as in that case LoaderDevicePartUUID is always set to the ESP, as that's where sd-boot is located, and sd-boot will set the var first, sd-stub will only set it later if it#s not set yet.)
