chore: fix some of FreeBsd compile issues. (#1374)

1. Use experimental/memory_resource because clang on freebsd does not support yet std::memory_resource
2. Pull latest helio with all the compatibility fixes.
3. Replace linux only SOL_TCP constant with IPPROTO_TCP (same value).
4. Fix build files to work on FreeBsd system.
