capabilities: Advertise cpuselection if -cpu host is usable
When -cpu host is supported by a QEMU binary, a user can use <cpu mode='host-passthrough'/> in domain XML even when libvirtd failed to find a matching model for the host CPU. Let's make it obvious by advertising <cpuselection/> guest capability whenever -cpu host is supported. Signed-off-by: Jiri Denemark <jdenemar@redhat.com>
