bitbake/bitbake-layers: fix to run with recent changes

This patch marks the bitbake-layers script as executable and fixes the
instantiation of the BBCooker to match recent changes in the BitBake
libraries.

I've also added a brief header which demonstrates the intent and usage
as taken from Chris Larson's original commit message.

Note: this fix is not upstreamable, it's only required in Poky because of an
outstanding difference between BitBake master and Poky's BitBake.
