albs-sign-node: albs-sign-node uses English locale explicitly but glibc-langpack-en is not installed in container

[metalefty]

albs-sign-node sets LANG=en_US.UTF-8, LC_ALL=en_US.UTF-8.

However, locale for en_US must be installed to use en_US.UTF_8. Signing will fail with the following error if the locale is not installed.

I'm not sure this issue is related to missing locales, LC_ALL should be fine AFAIK, isn't it?

The problem is LANG LC_ALL is set to en_US.UTF-8 although English locale glibc-langpack-en is not installed. en_US.* requires glibc-langpack-en.
