[Bug]: Wrong language after restart

[libook]

Describe the Bug

On the first start, the language is what I set. After I restart the container, the language change back to English.

It seems that LANG and LANGUAGE didn't work for Xfce; LC_ALL did.

So I have tried to remove the if condition in 40-setup_locale.sh, to let it process locale all the time. The language didn't change to English again.

Steps to Reproduce

1. Create the container.
2. Check the language.
3. Restart container.
4. Check the language again.
