vlc/python | branch: master | Odin Hørthe Omdal <odin.omdal at gmail.com> | Sat Sep  5 19:50:56 2015 +0200| [699c364e7e6218f599f1587351e567213f2c011c] | committer: Olivier Aubert

Fix setup.py to fall back to generated file

When you install python-vlc using pip or a similar package manager, you
won't have access to VLC files so you can't generate a fresh vlc.py.
However, the project itself ships a reasonably updated pre-generated
vlc.py that we can fall back to.
