Closes #72. There was two problems related to the way _nvidiaVersion was
detected.
nixGLCommon was using _nvidiaVersion in nix, which was failing
when using nix-env for search because, for yet unknown reason the
IFD readFile call was not working in this context.
all nvidia packages had their name set to contain the auto-detected
version, which leads to error on a system where the version cannot be
auto-detected. This is fixed, now the version is either unknown if
not explicitly fixed, or known.
