[pve-devel] Add modern cpu models

[Derumier Alexandre]

Since qemu 0.13, new cpu model exists through a config file : target-x86_64.conf.

http://wiki.qemu.org/Features/CPUModels

target-x86_64.conf currently exist in /etc/qemu , but this is the wrong directory as we use /etc/kvm

also, upstream target-x86_64.conf is not the last version.
The redhat owner developper had made cpu flags bugfix and add new models.

So I put the target-x86_64.conf from rhel 6.2.

New cpu models are:  (kvm -cpu ?)

Intel specific
