🐛 Fix entrypoint crash on __setup_mta ssmtp failure 🐛

__setup_mta calls __find_replace on /etc/ssmtp/revaliases which returns
1 when the symlink it creates is broken. With set -o pipefail active the
non-zero return kills the entire entrypoint before any command can run.
ssmtp is not installed in this image and email delivery is not a feature
of this image, so the MTA setup failure is irrelevant. Guard the call
with || true so initialization continues regardless.
