Provide a way to redefine the names of normal and fallback via CBFS.
This way updates can use some more expressive naming scheme (numbers,
dates, version numbers) and replace the coreboot-stages file to
point to the new version (with the current version as new "old").
If coreboot-stages doesn't exist, the default behaviour remains to
use "normal" and "fallback".
