bitbake: bin/bitbake, bb/__init__: Move BBDEBUG handling to bin/bitbake

The method this older code was accessing doesn't exist. A library shouldn't
be changing behaviour based on the environment anyway when sepcific function
calls exist to correctly setup the logging. Fix the crash if BBDEBUG was used
by moving the code to bin/bitbake.
