Disable local F13 repo by default

This allows the iso build process to automatically download packages
from the fedora repo, and doesn't require the user to manaully
prepare a local F13 repository by copying packages from the installation DVD.

If a user is willing to make such preparations manually, however,
it is always possible to enable this repo easily.
