[libvirt] [PATCH] qemu: Filter ARAT CPU feature from host-model

[Jiri Denemark]

ARAT feature was first introduced in QEMU 2.4.0, which means host-model
CPU mode is unusable with QEMU < 2.4.0 on any host CPU which supports
ARAT. Let's not include this feature in host-model CPUs unless a user
explicitly asks for it.

Notes:
    We will do this properly in the future since we will ask QEMU what CPU
    features it understands and what it thinks about host CPU. However, the
    required QMP interface is not upstream yet.
