Subject: poky-init-build-env: Breakup the environment script

Break up the scripts/poky-env-internal into two parts:
  1) Chunk that is sourced and sets up the environment
  2) Chunk that is executed and configures the build directory

OEROOT configuration was moved into the initial poky-init-build-env script.
