add +sep cpuflags to kvm32 && kvm64 cpu models

Need for win8 boot.

This flag was missing from rhel < 6.4 host kernel. It's ok now.
But it's also missing from kvm64 model. (It's exist in other cpu models, amd or intel).
So it's pretty safe to enable it.
If the host kernel is older, qemu filter the flag.

This also improve performance of winxp && win7 32 bits guests.
