Fixed a network setup issue for F19

IP address is passed as a kernel boot param when booting undercloud
machine. For Fedora 19, this IP is not set, instead IP is fetched
from DHCP.

The problem is caused by a bug in dracut-network version 029, which
causes that dracut network setup script is not executed properly. This
patch applies a fix for the bug when building undercloud image.

Fixes: bug #1213833
