[Buildroot] [PATCH v2 2/2] package/opencv3: ensure the python module works when BR2_PACKAGE_PYTHON{, 3}_PYC_ONLY=y

 > When BR2_PACKAGE_PYTHON{,3}_PYC_ONLY=y, the .py files are all removed,

 >   File "usr/lib/python3.7/site-packages/cv2/__init__.py", line 89, in <module>
 >   File "usr/lib/python3.7/site-packages/cv2/__init__.py", line 58, in bootstrap
 >   File "usr/lib/python3.7/site-packages/cv2/__init__.py", line 56, in load_first_config
 > ImportError: OpenCV loader: missing configuration file: ['config.py']. Check OpenCV installation.

 > To fix this problem, this commit uses the newly introduced
 > <pkg>_KEEP_PY_FILES mechanism, to ensure the important config*.py
 > files are kept.
