    rdp-fuse-clipboard: Always explicitly use global main context
    
    While g_main_context_get_thread_default() refers in the context of the
    timeout_reset_source creation to the global main context, this function
    can technically also return a different main context.
    The intention is, however, that the timeout_reset_source always runs on
    the main thread.
    
    Thus, change the main context, to attach the GSource to, to NULL, which
    refers to the global main context.
