    GDBus: make use of reliable async cancellation
    
    Call g_simple_async_result_set_check_cancellable() after all
    GSimpleAsyncResult creation in order to take advantage of the new
    reliable cancellation feature.
    
    The guarantee of reliable cancellation fixes a bug in dbusmenu (which
    was already assuming that cancellation was reliable).  See this bug:
