[SoaS] [PATCH] customization-guide : kickstart from the fedora13 branch

[tom-ipp]

Hello one more time,
as a user of the guide, it wasn't clear for me if I was building a soas
from rawhide or from F13.
To clarify, I add the reference to git checkout F-13 and moved the not
so clear note after the reference to git clone.
The patch :
