package/python-txtorcon.mk: drop _py3 file for python 2.x to fix pycompile issue

python-txtorcon DOES support python 2.x, but it contains some optional
python 3 / async code in controller_py3.py which is conditionally used from
controller.py:

try:
    from .controller_py3 import _AsyncOnionAuthContext
    HAVE_ASYNC = True
except Exception:
    HAVE_ASYNC = False

pycompile unfortunately errors out on the async code:

../scripts/pycompile.py ..
error:   File "/usr/lib/python2.7/site-packages/txtorcon/controller_py3.py", line 13
    async def __aenter__(self):
            ^
SyntaxError: invalid syntax

As a workaround, simply drop the unusable _py3 file from TARGET_DIR if
building for python 2.x.
