rke2-killall.sh does not remove calico or cilium interfaces

[manuelbuil]

rke2-killall removes the canal interfaces but not the interfaces created by cilium or calico: https://github.com/rancher/rke2/blob/master/bundle/bin/rke2-killall.sh#L67-L72

That will create problems in case of redeploying changing the cni. For example, when deploying with cilium and removing rke2, these interfaces remain:

35: cilium_net@cilium_host: <BROADCAST,MULTICAST,NOARP,UP,LOWER_UP> mtu 9001 qdisc noqueue state UP group default qlen 1000
    link/ether 7a:f2:4b:6a:fe:98 brd ff:ff:ff:ff:ff:ff
    inet6 fe80::78f2:4bff:fe6a:fe98/64 scope link 
       valid_lft forever preferred_lft forever
36: cilium_host@cilium_net: <BROADCAST,MULTICAST,NOARP,UP,LOWER_UP> mtu 9001 qdisc noqueue state UP group default qlen 1000
    link/ether 4e:5e:22:41:c6:cb brd ff:ff:ff:ff:ff:ff
    inet 10.42.0.193/32 scope link cilium_host
       valid_lft forever preferred_lft forever
    inet6 fe80::4c5e:22ff:fe41:c6cb/64 scope link 
       valid_lft forever preferred_lft forever
37: cilium_vxlan: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9001 qdisc noqueue state UNKNOWN group default qlen 1000
    link/ether 46:cd:bc:30:f6:3b brd ff:ff:ff:ff:ff:ff
    inet6 fe80::44cd:bcff:fe30:f63b/64 scope link 

We should remove all possible interfaces to avoid problems

Validated using install script from master at get.rke2.io

Initial ip link showed:

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 9001 qdisc mq state UP mode DEFAULT group default qlen 1000
    link/ether 06:be:e8:ef:40:94 brd ff:ff:ff:ff:ff:ff

Confirmed that running sudo rke2-killall.sh after bringing up rke2 with calico, canal, and cilium brought back that original output. Before running killall, there were extra interfaces from the cni running.
