Subject: Manual conversion of Baserock's build-essential stratum

This huge commit is a manual conversion, notes on what was
needed:

  o project.conf defines the arch specific stuff which was
    previously hardcoded into YBD, so the stage1 target and target
    etc are all defined by the build-essential project.conf

  o Direct and easy changes for git source representation

  o Added stage1.bst & stage2.bst "stacks", everything built in
    stage2 build-depends on stage1.bst, and the final build-essential
    products build-depend on stage2.bst (note build-depend means
    to depend _only_ for building, not propagated forward).

  o Instead of using host tools we build on the GNOME flatpak
    sdk/platform bundles

  o Some build-essential morph files use $(dirname $(pwd)) for a sysroot,
    which is weird, it means the morph files rely on building at one directory
    below the slash sysroot - in buildstream we build in /buildstream/build
    which is two - had to replace these with $(dirname $(dirname $(pwd))) instead

  o Remove the devices sections from the fhs-dirs elements, not allowed
    to create static device nodes in buildstream.
