Subject: [PATCH] lib/nvm: Use `which nvm` and `nvm current`

This makes it work regardless of where nvm is loaded from. And it uses nvm's version strings, which distinguish the "system" and "none" NVM environments, instead of reporting the specific version of the system node.js or erroring, respectively.
