tests: qemublock: Add synthetic snapshot+checkpoint test data

Add a faked qemu output which would simulate scenario where libvirt
would take a snapshot and checkpoint simultaneously. This is visible in
libvirt-2-format node where bitmap 'c' appears, but bitmap 'b' which is
active in the previous layer is not present.
