What would the config look like?  AFAICS our ‘nginx’ package doesn’t
embed Perl, and I think it’s better this way.  :-)  Can we do that with
pure nginx directives?

We create /srv/guix.gnu.org (as a symlink) with the correct mtime¹.  If
we can tell nginx to use it as the ‘Last-Modified’ date, that’s perfect.
