[PATCH 4/8] tests/qtest: Add -vga none by default

[Juan Quintela <quintela@redhat.com>]

Nothing in qtest where using vga by default except for
dbus-display-test.  We add -device VGA there.

The only other test that fails after this change is:

(test program exited with status code -6)
------------------------------------------

Problem is with virtio-iommu-test.c attach_detach test.  My
understanding is that the problem is that for pseries.

$ export QTEST_QEMU_BINARY=./qemu-system-ppc64
$ ./tests/qtest/qos-test -p /ppc64/pseries/spapr-pci-host-bridge/pci-bus-spapr/pci-bus/virtio-iommu-pci/virtio-iommu/virtio-iommu-tests/attach_detach

Bail out! ERROR:../../../../mnt/code/qemu/full/tests/qtest/virtio-iommu-test.c:189:test_attach_detach: assertion failed (ret == 0): (6 == 0)
Aborted (core dumped)

My understanding is that if I remove the vga device, pseries end
without any device on the pci bus and somehow it completely breaks.
