This PR will use the system installed version of Node.js and avoid printing a warning or error if a discontinued version is selected. This optimization was already in `@now/node` but for some reason it was never add to `@now/next`. The reason why its relevant today is because the warnings turned into errors due to Node 8 deprecation and we don't have the "Project" in `now dev` so we don't know which version of node to select. So instead of determining the version, `now dev` will always use `node` in the PATH and avoid printing warnings or errors. This also results in less FS reads since we no longer need to read package.json.
