Personal Submodule Forks and Docker Build

- Modify ec, coreboot, and edk submodules to point to personal
  forks using relative URL path
- Add image and script to build firmware in docker container
- Move firmware update build steps from flash.sh to build.sh
  so it can be built inside docker container
