Subject: [PATCH] nixos/libretranslate: fix stdout logging

Currently, the libretranslate service does not appear to output any
logs to the systemd journal, even though it prints log lines to stdout
when run outside of a systemd service. This commit fixes the problem by
setting PYTHONUNBUFFERED to disable Python's stdout buffering.
