On linux use sysfs instead of lscpu Use sysfs (https://www.kernel.org/doc/Documentation/ABI/stable/sysfs-devices-node) to determine processor to NUMA node mapping. Avoids problems on some machines with high core count where lscpu was showing high cpu utilization. closes https://github.com/official-stockfish/Stockfish/pull/5315 No functional change
