appFolder: Don't block all shortcuts

App folder popups take a grab when opened, and as we don't pass any
particular pushModal() parameters, all keybindings are blocked. While
this makes sense for most keybindings that would interfere with the
popup interaction, others like volume/brightness keys or screenshots
can be allowed safely.
