base: remove lang.sh

When entering the container we always get this annoying warning:

bash: warning: setlocale: LC_CTYPE: cannot change locale (en_US.UTF-8): No such file or directory
bash: warning: setlocale: LC_COLLATE: cannot change locale (en_US.UTF-8): No such file or directory
bash: warning: setlocale: LC_MESSAGES: cannot change locale (en_US.UTF-8): No such file or directory
bash: warning: setlocale: LC_NUMERIC: cannot change locale (en_US.UTF-8): No such file or directory
bash: warning: setlocale: LC_TIME: cannot change locale (en_US.UTF-8): No such file or directory

Because the locale is not available, to fix this issue let's remove the
lang file which contains the local to set.
