Preserve the hypervisor bit while KVM trims the CPUID bits
The KVM kernel will disable all bits in CPUID which are not present in
the host. As this is mostly true for the hypervisor bit (1.ecx),
preserve its value before the trim and restore it afterwards.
This is similar to commit 6c0d7ee8, but since qemu-kvm uses another code
path it has to be inserted in qemu-kvm-x86.c, too.
