Create a wrapper for nvidia install

Browse Source 
Hash of nvidia driver is not known because it depends on the driver version
(argument `nvidiaVersion`). However, since nix 2.0 and when using `useSandbox`,
`sha256 = null` is not allowed anymore.

The new wrapper script, `nvidiaInstall.py` uses `nix-prefetch-url` to compute
the hash and call `nix`.

This is a fix for #9

## Install
The previous commands only build the wrapper, now stored inside `./result`, you need to install it:
```
