Use xkb_keymap_new_from_buffer instead of xkb_keymap_new_from_string

Browse Source 
xkb_keymap_new_from_string just calls xkb_keymap_new_from_buffer with size as `strlen(string)`.

0f1cae0cc4/src/keymap.c (L164)

According to the [spec](https://gitlab.freedesktop.org/wayland/wayland/-/blob/master/protocol/wayland.xml#L2182), MAP_PRIVATE should be used.
