npm install before meteor build

[athyuttamre]

If a Meteor app has npm dependencies listed in package.json, we need to run npm install (or perhaps npm install --production) before building the bundle.

Per this guide section:

Any npm dependencies must be installed before issuing the meteor build command to be included in the bundle.

Could you add a line to install npm dependencies before building the app?

Added; docker hub image updated. Let me know if this works for you. I do not use this feature.

I'm not able to test anytime soon, but the commit looks good to me. If you wanted to be careful, you could do meteor npm install --production so the Node version matches the version that Meteor is using.
