Migrating to base image nodejs:4.2.

- Remove dbus, it's unnecessary and we can no longer run it in the background without the phusion-baseimage's init process.
- Remove setuser calls since that script no longer exists without phusion-baseimage, instead do all as root (will make files read-only for the app user which is more secure anyways).
