By looking at the code, it seems that it was a goal to make the sudo wrapper path configurable through the Vagrantfile, but it wasn't effective and didn't make much sense (that kind of config is a per-host config, not a per-guest one). This caused the cause to be needlessly complex by giving the Provider the responsibility of instanciating the wrapper. This commit gets rid of that. I didn't get rid of `sudo_wrapper` injection in `Driver` and `Driver::CLI` constructors because they're needed for tests. I'm not ready to tackle this yet.
