Add mes and mescc-tools-extra
mescc-tools-extra contains two important tools: - cp - chmod mes first builds itself from a mes 0.21 seed as used by guix, and then builds a mes 0.22 and then mes 0.22 using that created mes 0.22. It does /not/ use bootstrap.sh as we don't have a proper shell at this point, it has been manually adapted for kaem.
