This change causes the following RuntimeError exception, when running bitbake
(any bitbake command):

$ python --version
Python 2.7.9
$ bitbake
Traceback (most recent call last):

Even though .../poky/bitbake/lib is already in the sys.path,
.../poky/bitbake/lib/toaster is also added, which seem to be the cause of this
issue.

I'm a bit surprised that this kind of change causes issues for use of bitbake
not related to toaster.
