Unlike other features we have enabled earlier, this one requires
version checks because RISC-V guests have only started using PCI
by default very recently, and we can't have USB without PCI.
More specifically, we need QEMU commit d6c1bd4a2237 (included
in 4.0.0) and libvirt commit 7c48fb08e0cd (included in 5.3.0).
