Feature Request: LAMA_LOG_FILE env variable.

Prerequisites

• I am running the latest code. Mention the version if possible as well.
• I carefully followed the README.md.
• I searched using keywords relevant to my issue to make sure that I am creating a new issue that is not already open (or closed).
• I reviewed the Discussions, and have a new and useful enhancement to share.

Feature Description

For Docker users who rely on an environment file, it would be helpful if LLAMA_LOG_FILE could be supported in the same way as the other logging options.

Motivation

This would make logging configuration consistent and avoid the need to override command: in docker-compose.yml. At the moment, the llama.cpp server supports several logging options via environment variables (e.g. LLAMA_LOG_VERBOSITY, LLAMA_LOG_PREFIX, LLAMA_LOG_TIMESTAMPS, LLAMA_LOG_COLORS).

However, --log-file only works when passed as a CLI flag and does not appear to have an environment variable equivalent.

Possible Implementation

Should be fixed in #17609 :)
