selftest-setup test in ubuntu_kvm_unit_test will fail on Artful/Bionic s390x zKVM

[Po-Hsu Lin]

Issue spotted on node s2lp6g004 (Artful zVM works fine)

Steps:
 1. git clone --depth=1 https://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git
 2. cd kvm-unit-tests; ./configure; make
 3. TESTNAME=selftest-setup TIMEOUT=90s ACCEL= ./s390x/run s390x/selftest.elf -smp 1 -append 'test 123'

Result:
timeout -k 1s --foreground 90s /usr/bin/qemu-system-s390x -nodefaults -nographic -machine s390-ccw-virtio,accel=tcg -chardev stdio,id=con0 -device sclpconsole,chardev=con0 -kernel s390x/selftest.elf -smp 1 -append test 123 # -initrd /tmp/tmp.8qFJLS3Adb
