Install the anaconda-live package on the live image
Recently all Anaconda files required only for the live installation
(the liveinst script, the desktop file and others) have been split into a sub-package
called anaconda-live.
This was done to prevent these files from littering both network
installation images as well as user systems when Anaconda gets pulled
in as a dependency during a package installation transaction.
At the moment anaconda-live is stilled pulled in as a direct dependency
of the anaconda-gui sub package, but once this commit has been merged
into the Fedora kickstart repository, we can drop this temporary
dependency, removing the package from non-live installations.
