wayland/keyboard: Don't transfer layout group when replacing xkb state

Browse Source 
The layout group determines what actual keyboard layout in the keymap
to use when translating modifier state and key codes to key syms.
When changing a keymap to another, the layout groups has no relation to
the layout groups in the old keymap, thus there is no reason to
transfer it to the new state.

This fixes an issue where the xkb state in meta-wayland-keyboard.c got
desynchronized with the xkb state in clutter-device-manager-evdev.c.
