Add nodejs support for 32bit architectures

Nodejs installation fails silently on 32-bit systems -- the issue only affects provisioning if you install any npm packages through puppet, otherwise the install appears to finish successfully, but will create non-executable binaries.

Installing an npm package via puppet:

```bash
Error: /Stage[main]/Main/Package[bower]: Could not evaluate: Puppet::Util::Log requires a message
```

Running `node` in the terminal:

```bash
vagrant@system:/usr/local/bin$ node --version
-bash: /usr/local/bin/node: cannot execute binary file: Exec format error
```

Running `npm install` in the terminal:

```bash
vagrant@system:~$ npm install
