Description of problem:
Network device on installed system is not configured with static IPv4 address used during manual installation on s390x. There is no ifcfg config file created on the installed system either:

[root@rtt8 ~]# ls /etc/sysconfig/network-scripts/ifcfg*

When running installation on x86_64 with manually entered static IPv4 configuration during the installation, an ifcfg config file is created on the installed system and the configuration is applied during boot.

Version-Release number of selected component (if applicable):
Fedora-Rawhide-20190707.n.0
anaconda 31.18-1.fc31

How reproducible:
always

Steps to Reproduce:
1. Run installation of rawhide on s390x
2. Reboot into installed system

Actual results:
Network device is available, but has no IPv4 address assigned

Expected results:
Network is up, with IPv4 address assigned
