[mirror-admin] Fedora 7/8+updates going away

[Mike McGrath]

We're moving Fedora 7 and Fedora 8 to our archives.fedoraproject.org
server.  You can still sync the content there.  Unfortunately our plan to
have the master mirrors upgraded by now hasn't happened yet so we're just
running out of space.

I'll be removing the 7/8 content from the master mirrors sometime tomorrow
replacing it with a README like we have the others.
