Show current keyboard layout at the sudo window

[ppronini]

Currently when you try to install updates, etc you need to enter your sudo password, for that there a specific window where you need to enter that, and it shadows the background. When you actively use various keyboard layouts, i.e. Russian, you don't see the language currently used, so you have to show password to see what characters you are typing now. It would be great to see keyboard layout at that screen like at lock screen.
