Bug#984876: openssh-server: logs unsightly errors from pam_env due to missing /etc/default/locale

Package: openssh-server
Version: 1:8.4p1-4
Severity: minor

Dear Maintainer,

I installed openssh-server in an autopkgtest VM for debugging.  It works
fine, but pollutes the logs with red messages like

sshd[2122]: pam_env(sshd:session): Unable to open env file: /etc/default/locale: No such file or directory

The locales package is not installed on this VM, but I didn't do
anything for that.

In my opinion it would be nice to get rid of that error is possible.
Apparently it comes from /etc/pam.d/sshd:

# In Debian 4.0 (etch), locale-related environment variables were moved to
# /etc/default/locale, so read that as well.
session    required     pam_env.so user_readenv=1 envfile=/etc/default/locale

Or should (for example) base-files make sure it exists?
