node: npm 2.1.6
node: move more npm logic to install, cleanup.

Do `make uninstall install` to better match the upstream install script,
don't copy files around unnecessarily when the installer will do it,
tell npm to use verbose output when we install it and don't
automatically install the latest version (entropy is bad).
