The configuration file is processed sequentially, which meant that there was
no way to set for example log format shared between the server-blocks, because
the final configuration file would have this order:
...
http {
...
server {
}
...
$extra-content
}
Moving the extra-content before the serialization of server-blocks resolves
this.
* gnu/services/web.scm (default-nginx-config): Move extra-content before
server-blocks.
