    build: depend on tools/zstd for download
    
    Downloading packages from git requires zstd to compress their tarballs.
    Make sure that zstd from host tools is compiled when running make
    download. Otherwise, either the download would fail because zstd is not
    present or a random version from the host would be used leading to hash
    mismatches.
