[PATCH 2/4] tests/qtest: Check for virtio-blk before using -cdrom with the arm virt machine

[Thomas Huth <thuth@redhat.com>]

The arm "virt" machine needs "virtio-blk-pci" for devices that get attached
via the "-cdrom" option. Since this is an optional device that might not
be available in the binary, we should check for the availability of this
device first before using it.
