feat(docker): split build and runtime stages

* Separate build and runtime environments to streamline image layers
* Add missing dev dependencies for building and runtime dependencies for serving
* Use `lighttpd` as the runtime web server and move configuration files
* Pass custom build option to `make` for improved compatibility
