Isn't this only going to work if you require foreman-assets?

Precompilation requires quite a different approach which we haven't tackled yet in Debian packages.  In RPMs, we put foreman-assets as a build dependency, install the plugin, then run `rake plugin:assets:precompile[plugin_name]`, then package the resulting files from public/assets/gem_name/ inside the plugin (gem) root.
