Close #4895

This PR added an environment variable OLLAMA_NO_MMAP to ollama serve. When this environment variable is set to 1, --no-mmap param is always added to llama runner.

This PR will not bring any breaking change. If this environment variable is not set, mmap will keep enabled except pre-defined condition.
