This fixes bz1854037 which happens because kexec-tools generates rd.route for
eth0 instead of for kdump-eth0,
1. "rd.route=168.63.129.16:10.0.0.1:eth0 rd.route=169.254.169.254:10.0.0.1:eth0" is passed to the dracut cmdline by kexec-tools
2. In the 2rd kernel, dracut/modules.d/35network-manager/nm-config.sh calls
/usr/libexec/nm-initrd-generator to generate two .nmconnection files
based on the dracut cmdline, i.e. kdump-eth0.nmconnection and eth0.nmconnection,
- /run/NetworkManager/system-connections/kdump-eth0.nmconnection
[connection]
id=kdump-eth0
uuid=3ef53b1b-3908-437e-a15f-cf1f3ea2678b
type=ethernet
autoconnect-retries=1
interface-name=kdump-eth0
multi-connect=1
permissions=
wait-device-timeout=60000
[ethernet]

3. Since there's eth0.nmconnection, NetworkManager will try to get an IP for eth0 regardless of the fact it's a slave NIC and time out
```
$ ip link show
2: kdump-eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
link/ether 00:0d:3a:11:86:8b brd ff:ff:ff:ff:ff:ff
3: eth0: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master kdump-eth0 state UP mode DEFAULT group default qlen 1000
```
