tests: Fix use of virtio-serial for aarch64/virt

virtio-serial is an alias for virtio-serial-pci, which
should not have been used for a PCIe-less aarch64/virt
guest but it ended up being used anyway because the
virtio-mmio capability was missing and the algorithm
is buggy.

Fix the test case so that we can fix the algorithm next.
