All definitions related to Hyper-V emulation are now taken from the QEMU
own header, so the one imported from the kernel is no longer needed.

Unfortunately it's included by kvm_para.h.

So, until this is fixed in the kernel, teach the header harvesting
script to substitute kernel's hyperv.h with a dummy.
