nodejs cartridge: use npm install --production

In the [npm config doc](https://www.npmjs.org/doc/misc/npm-config.html)  it's explained that `-d` means `--loglevel info`.

Moreover,

> By default, npm install will install all modules listed as dependencies. With the --production flag, npm will not install modules listed in devDependencies.

`devDependencies` are used for tests. We don't want to download tests dependencies when we deploy to openshift. It will make build faster for nodejs projects.
