Emergency update to kojiweb.conf

[Dennis Gilmore]

I just made a minor change to kojiweb.conf

RewriteRule ^/koji/login$ https://koji.fedoraproject.org/koji/login

koji-1.2.6 only allows you to use ssl when logged in.  by rewriting the login 
you end up using https 

without the change a user would need to go to https before trying to login or 
they would get a traceback trying to login.
