    main: don't hook up overview keybinding until after startup
    
    Toggling the overview during the startup animation reportedly
    causes stuck grab and other odd behavior.
    
    There's no reason to handle toggling the overview during this
    time anyway.
    
    This commit defers that handling until after startup.
