Export the kernel partition's UniqueGuid to the kernel command line.

This will cause a %U in the kernel command line to be replaced with the
human-readable form of the kernel partition's UniqueGuid, which is passed
from the Chrome OS BIOS. If the BIOS doesn't pass this information (older
ones don't), %U expands to 00000000-0000-0000-0000-000000000000.
