This commit removes unnecessary `proxy_set_headers` in the serve
static config block.
Indeed, the request will either be served by Nginx in which case
the request won't go to the proxy backend or by the `@odoo` backend
which have its own `proxy_set_headers` set as the user is supposed
to copy/paste the contennt of the `location /` block.
