Add the coreboot config to CBFS
The CBFS will contain a new file, named 'config' of type 'raw' that
is a stripped-down stripped-down version of the .config file that
was used to build coreboot. For space savings, all the comments and
empty lines were removed from the original config.
This is done in order to easily reproduce the process of creating an
image made by someone else when only having the original binary
image.
Known issues/TODOs:
-when using abuild, the generated images will contain the config from
the coreboot tree, if anf only if this exists, and not the config file
generated for the current board by abuild.
-the coreboot git revision is not listed in the config file as of yet.
