[PATCH] Don't write out firewall settings if they already exist (#502479)

[Jeremy Katz <katzj redhat com>]

(Side commentary: this sort of thing is getting a little bit out of hand, we 
should probably think a little on if there's a better way for us to handle 
this sort of thing)

livecds could already have custom firewall settings, so let's not
overwrite them for now
