Use www.coreboot.org over coreboot.org

<https://coreboot.org> is redirected to <https://www.coreboot.org>.

```
$ curl -I https://coreboot.org
HTTP/1.1 301 Moved Permanently
Server: nginx/1.8.1
Date: Mon, 05 Jun 2017 10:41:33 GMT
Content-Type: text/html
Content-Length: 184
Connection: keep-alive
Location: https://www.coreboot.org/

```

So use the command below to use the final location to save a redirect.

```
$ git grep -l https://coreboot.org \
| xargs sed -i 's,https://coreboot.org,https://www.coreboot.org,g'
```
