bitbake: Move the logger initialization from cooker to utils

In order to move the environment cleaning, which wants to log a
message, before cooker creation, the logging facility initialization
needs to happen earlier.  So, it is now in init_logger in utils.py and
called from bitbake before the creation of the data object.

It also seems more correct to initialize a global facility like this
from a more global context than the creation of an object, of which
there could theoretically be many.
