footer: change source link to relative

i've tweaked cgit to serve aaoth.xyz repo under /src/*. now source code
is available through yggdrasil, tor and i2p without leaving the site.

in httpd.conf it looks like this:

```
...
location "/src/*" {
    root "/cgi-bin/cgit.cgi"
    fastcgi {
        socket "/run/slowcgi.sock"
        param CGIT_CONFIG "/cgit/cgitrc-embed"
    }
}
...
```

so i'm just pointing cgit to other configuration file which is tweaked to
fit for this purpose (e.g. noheader option is turned on and there's no
scan-path, just one repo).
