This PR changes the way we set the shlib directory helper. Instead of setting it while initializing the Host plugin, we register it when initializing the Python plugin. The motivation is that the current approach is incompatible with the dynamically linked script interpreters, as they will not have been loaded at the time the Host plugin is initialized. The downside of the new approach is that we set the helper after having initialized the Host plugin, which theoretically introduces a small window where someone could query the helper before it has been set. Fortunately the window is pretty small and limited to when we're initializing plugins, but it's less "pure" than what we had previously. That said, I think it balances out with removing the plugin include.
