Avoid jemalloc messages on low-end virtual machines

Official CH changelog text
Avoid printing a message from jemalloc about per-CPU arenas on low-end virtual machines. #65532 (Alexey Milovidov).
Suppress jemalloc messages about per-CPU arenas on low-end virtual machines to reduce unnecessary logging noise.

Why it matters

On low-end virtual machines, jemalloc prints messages related to per-CPU arenas which can clutter logs and cause confusion. This change prevents those messages from appearing, improving log clarity and reducing distractions for users monitoring their systems.

How to use it

This feature is enabled automatically with the updated ClickHouse version. No additional configuration is needed from the user to benefit from suppressed jemalloc messages.
