Add support for specifying where the kickstart file will be created:
either in the default location in the anaconda tree or at the root of
the ISO like we did so far in RHEL.
From the distro level, this is controlled by a boolean that when set to
true puts the kickstart file in the root of the ISO tree at /osbuild.ks
(the old behaviour) and if unset falls back to the default location
/usr/share/anaconda/interactive-defaults.ks.
Changed the name of the kickstart file for ostree back to osbuild.ks
Was ostree.ks for a while since a1bfcfe91c.
For Fedora we use the default and for RHEL we maintain the old behaviour
for now.
