Don't search "Keyboard at" from hyprland/language

The current output form of `hyprctl devices` is like this:
```
        Keyboard at 6f80ad70:
                ITE Tech. Inc. ITE Device(8910) Keyboard
                        rules: r "", m "", l "us,ru", v "", o "grp:alt_shift_toggle"
                        active keymap: Russian
                        main: no
```

That is, `Keyboard at` goes _before_ the keyboard name, so looking for `Keyboard at` only makes it skip to the keyboard _after_ the one that the user specified.
