README.md: for Ubuntu cv2.so changed to cv2.x86_64-linux-gnu.so

[tgianko]

Hi,

In Ubuntu 16.04.3 LTS cv2.x86_64-linux-gnu.so is the correct name instead of cv2.so. I believe this should be used instead:

sudo apt-get install python-opencv
ln -s /usr/lib/python2.7/dist-packages/cv2.x86_64-linux-gnu.so NEON/.venv/lib/python2.7/site-packages/

with NEON is the installation path of neon.

Excuse me, but did you ever get the full implementation of this project to work? If so could you help me?
