Change bootstub POST codes to B0B0 (enter) and EEEE (fail).

The bootstub was emitting C0DE at entry and DEAD for failure. With only an
8-bit POST code monitor attached to port 80, it is not immediately clear
whether "DE" is from the entry point or the failure point.

B0 and EE are not currently used in x86 BIOS, AFAIK.

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
