bitbake.conf: Set ZSTD_THREADS to half of cpu numberrbt/zstd
The original value is very easy to cause do_packge error when cpu number is larger, for example, 128 cores and 512G mem: error: create archive failed: cpio: write failed - Cannot allocate memory" Set the ZSTD_THREADS to half of the CPU number can avoid the error in my testing.
