main/py-bluez: add missing py2-setuptools dependancy to fix failing build

After commit f9ef1aaa that renamed py-setuptools, the build of py-bluez fails with error

Traceback (most recent call last):
  File "setup.py", line 3, in <module>
    from setuptools import setup, Extension
ImportError: No module named setuptools
>>> ERROR: py-bluez: build failed

Adding py2-setuptools fixes the issue.

Hm, I think it'd be better if we just switched this over to py3 only.

Thanks for your contribution

needed for kodi

Kodi is such a pain and keeps all the python2 stuff still there
