in qt5, gtkstyle use gtk_widget_send_focus_change, this had a side
effect that will trigger real gtk im module, if qt load the same qt and
gtk im module for same input method, it will cause conflicts for qt im
module. The only gtk widget have im-module property is GtkEntry and
GtkTextView, since only GtkEntry is used here, we only need to override
im-module for GtkEntry.
gtk-im-context-none exists in gtk+ since 2.19.5, and for older version,
it will also harmlessly fallback to gtk-im-context-simple.
