Martin Kosek 3896bf370a Change network configuration file
Fedora+systemd changed deprecated /etc/sysconfig/network which was
used by IPA to store static hostname for the IPA machine. See
https://bugzilla.redhat.com/show_bug.cgi?id=881785 for details.

Change Fedora platform files to store the hostname to /etc/hostname
instead.
