[PATCH 4/4] Fix potential ssh/nfs kdump failure of missing "ip" command

For ssh/nfs dump, kdump need the 'ip' tool to get the host ip address for naming the vmcore. But kdump-module-setup.sh never installed this tool. kdump-module-setup.sh worked so far as dracut network module will help install it. After dracut changed to use 35network-manager for network setup, "ip" command won't be installed in second kernel by default. So need to ensure "ip" is installed when installing kdump dracut module.
