ui/vnc-clipboard: fix adding notifier twice
vnc_server_cut_text_caps() is not guaranteed to be called only once. If it called twice, we finally call notifier_list_add() twice with same element. Which leads to loopback QLIST. So, on next notifier_list_notify() we'll loop forever and QEMU stuck. So, let's only register new notifier if it's not yet registered. Note, that similar check is used in vdagent_chr_recv_caps() (before call qemu_clipboard_peer_register()), and also before qemu_clipboard_peer_unregister() call in vdagent_disconnect() and in vnc_disconnect_finish().
