kata-deploy: QEMU, for 2.x, already includes virtiofs

There's no reason to ship qemu & qemu-virtiofs when the former already
includes vitiofs support (and that's the default for 2.x deployments).

In case we will enable experimental qemu DAX support, we should add a
new target, a "qemu-experimental" target, as Carlos has been working on.

Fixes: #1424
