[vlc-devel] [PATCH 2/2] Fix setup.py to fall back to generated file

[Odin Hørthe Omdal]

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.
