[libsigc++2/variadic] exception_catch_functor::operator():

[Murray Cumming <murrayc src gnome org>]

commit f6f4204a0831efad73c1dbb4f58fd82058fc9d04

    exception_catch_functor::operator():
    
    Remove the unnecessary operator()() overload.
    This did need me to change the test code so that it doesn't try to
    provide a catch function that returns something, but that seems
    more correct anyway.
