x11: on grabbed hotkey press, send the hotkey's underlying key (xdoto…

In other words, if the hotkey isn't used for sending text (which we assume it isn't if the first command is something else, out of simplicity), it's okay for the key to be eaten up a bit. Doing the Send workaround does send something to X11 after all which could be undesired and should be avoided: See:
