GtkMenuTracker: fix signal handler argument list

The signal handler for the visibility of menu items changing had the
wrong signature, resulting in the GParamSpec from the notify signal
being treated as a boolean (which was always true).  This resulted in
items being added over and over and never being removed.

Fix that...
