package/python-pymodbus: drop asyncio files for python 2.x to fix pycompile issue
Pymodbus has optional support for asyncio. Pycompile unfortunately errors
out on these files when running under Python 2.x:
../scripts/pycompile.py ..
error: File "/usr/lib/python2.7/site-packages/pymodbus/client/asynchronous/asyncio/__init__.py", line 257
yield from self._connect()
^
SyntaxError: invalid syntax
As a workaround, simply drop the unusable files from TARGET_DIR if building
for python 2.x.
