Add the coreboot config to CBFS
The CBFS will contain a new file, named 'config' of type 'raw' that is a stripped-down version of the .config file that was used to build the current coreboot image. For space savings, all the comments and empty lines were removed from the original config, except for one that lists the coreboot git revision that's built into the image. This is done in order to easily reproduce the work of someone else when only having their ROM image. In theory the reproduce could even be automated by a new dedicated make target. This should work even with abuild now.
