bitbake|cooker: save a copy of the environment when BitBake is started

Create a data store in the cooker containing the values of the environment
from when BitBake is launched such that child processes can replicate
(and/or use values from) the host environment, rather than the cleaned up
environment that the main BitBake process uses.
