Avoid namespace collision with multi-webpack runtimes

[ellm]

If multiple webpack runtimes (from different compilations) are used on the same webpage, there is a risk of conflicts of on-demand chunks in the global namespace.

See: https://webpack.js.org/configuration/output/#outputjsonpfunction

When a conflict occurs, it causes a fatal JS error. I have experienced this behavior when a site bundle and Liveblog bundle are loaded on the same page.

According to Webpack documentation, changing output.jsonpFunction to a custom name will avoid the collision.
