fix node.js installation (32bit)

`NVM_DIR` was `~/.config/nvm` but it was supposed to be `~/.nvm`.

from the `nvm` install script output:
```
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion
```
