Fix zstd-pgo run error

The -Werror=missing-profile caused thread/zlib/lzma/lz4 detection failure
when build with profile-use, thus caused ZSTD_MULTITHREAD etc. is not
defined for profile-use, then there will be many profile mismatch information
in output and the final binary reports run error sometimes as below:

Error : ZSTD_CCtx_setParameter(ctx, ZSTD_c_nbWorkers, adv->nbWorkers) failed : Unsupported parameter
