tests/kola: ignore NIC ordering issues on s390x for team-dhcp-via-ignition

Browse Source 
On s390x, network interfaces use the CCW bus instead of PCI, which can lead to
wrong NIC ordering. This causes the team-dhcp-via-ignition test to
fail:
```
07:19:05  Jul 29 07:19:00 qemu0 kola-runext-test.sh[2336]: Error: get team0 ip = 10.0.2.32, expected is 10.0.2.31
```
This happens, because eth1 and eth2 are wrong ordered (altnames):
```
$ ip -o link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000\    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000\    link/ether 52:54:00:12:34:56 brd ff:ff:ff:ff:ff:ff\    altname enc2\    altname enx525400123456
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel master team0 state UP mode DEFAULT group default qlen 1000\    link/ether 52:55:00:d1:56:01 brd ff:ff:ff:ff:ff:ff\    altname enc4\    altname enx525500d15601
4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel master team0 state UP mode DEFAULT group default qlen 1000\    link/ether 52:55:00:d1:56:01 brd ff:ff:ff:ff:ff:ff permaddr 52:55:00:d1:56:00\    altname enc3\    altname enx525500d15600
5: team0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default qlen 1000\    link/ether 52:55:00:d1:56:01 brd ff:ff:ff:ff:ff:ff
```
