    express,fedora: Install from remote repo for <= F16
    
    Not sure if this is a good thing in general but this is the quickest
    solution to this bug I could come-up with:
    
    https://bugzilla.redhat.com/show_bug.cgi?id=804834
    
    One issue with this change is that it makes Fedora 16 (and older) express
    installation to require Internet access. On the bright side, we can now
    have spice-vdagent package installed automatically from the start.
