[PATCH v2 5/6] vhost: claim that we support GUEST_ANNOUNCE feature

[Yuanhan Liu <yuanhan.liu@linux.intel.com>]

It's actually a feature already enabled in Linux kernel. What we need to
do is simply to claim that we support such feature, and nothing else.

With that, the guest will send GARP messages after live migration.
