efl_ui_clickable: fix not to be clicked if pointer is processed

If pointer is processed by a container in its POINTER_MOVE event
callback, then clickable calls efl_ui_clickable_button_state_reset not
to be clicked by efl_ui_clickable_unpress.

e.g. Efl.Ui.Active_View.View_Manager_Scroll sets pointer processed in
POINTER_MOVE event callback not to click button during scrolling.
