vm/qemu: prevent network device renaming on s390x arch
This is a temporary work-around for s390x until it supports CONFIG_CMDLINE.
Failing to do so might cause a failure to establish a SSH connection
when syz-ci tests a built image.
syz-ci output:
--------------
building kernel...
testing image...
VM boot failed with: can't ssh into the instance
failure log:
------------
failed to run ["ssh" "-p" "34490" ... "root@localhost" "pwd"]: exit status 255
Connection timed out during banner exchange
Connection to 127.0.0.1 port 34490 timed out
qemu dmesg
----------
[ 6.646475] virtio_net virtio0 eno1: renamed from eth0
