The virDomainOpenGraphics API cannot label the socket we pass to it. Prefer virDomainOpenGraphicsFD (if building with libvirt 1.2.8 or later) which creates the socket for us and works with SELinux too. Fall back to the old API if the new one is unsupported (i.e. the libvirtd on the host is older than the libvirt version virt-viewer was compiled against).
