live base: Install fedora-release-nonproduct for non-product lives
    
    Add fedora-release-nonproduct to fedora-live-base.ks to ensure it gets
    pulled in for all spins. In order to avoid it getting pulled in to
    the Workstation product that is also based on fedora-live-base.ks,
    explicitly exclude fedora-release-nonproduct in workstation kickstart
    file.
