A simple patch to add serial console attribute to kickstart files Fedora

over look.

Hm, I actually purposely removed it from Fedora 14 (take a look at commit e884952569a95100d667cce8ca1c50a952a3f3fe), and the others were copied from that.  I honestly don't remember the exact circumstances, but clearly we were having some issues.  At this point, if you test it on Fedora 15, 16, 17, and 18 and it works OK, I'd be happy to add it back in.
