This adds heads to Guix. Heads is minimal Linux that runs as a coreboot or LinuxBoot payload to provide a secure, flexible boot environment for laptops and servers. Heads uses checksums to make sure that all the components are what they are supposed to be, at build time, at BOOT time and when resuming. Therefore, it's difficult to replace stuff with our versions. I'm not sure whether we should--since Heads is supposed to build the same thing reproducibly everywhere. A future version will be a variant which does replace Linux by Linux-libre, but that also changes both the source hashes and the output (and thus the output hashes).
