tools/libxc: Fix ARM build broken by XEN_DOMCTL_getvcpuextstate commit

The previous "tools/libxc: Exposed XEN_DOMCTL_getvcpuextstate" broke
the ARM build (the hypercall does not have a corresponding DOMCTL
ARM struct). This patch fixes the build by returning -ENODEV for
ARM from xc_vcpu_get_extstate().
