Add setting for custom nginx config

In my vhosts, I use an included file for an ACME location block. This PR adds the ability to append arbitrary nginx config to the ansible-installed vhost, which allows me to do what I need to do without needing to maintain my own copy of the entire vhost.

It adds a config var, funkwhale_nginx_additional_config, with an empty default.
