This commit introduces two changes.
First, cpython gets optional BlueZ support, which is needed for
AF_BLUETOOTH sockets. Therefore bluezSupport was added as a parameter.
Second, the call to the pythonFull packages has been adjusted. The
Python packages have a self-reference called self. This was not adjusted
for the override. As a result, Python packages for this special version
of Python were not built with the overridden Python, but with the
original one.
