[OE-core] [PATCH] runqemu: Use correct kvm CPU options for qemux86* with kvm

[Richard Purdie]

The existing -cpu host option caused kernel panics when people attempted to use
the kvm option. After research and discussion, the best options appear to
be the kvm32/kvm64 cpu types so lets use these instead. These resolve
the kernel issues for me.
