[chore](thirdparty) build hadoop_libs_3_4 on macOS too

What problem does this PR solve?

Related PR: #66783

Problem Summary:

build-thirdparty.sh adds the hadoop packages to its default package list under uname -s == Linux alone, so no macOS build has ever installed lib/hadoop_hdfs_3_4/ — neither a developer's local prefix, nor the doris-thirdparty-prebuilt-darwin-x86_64 / -arm64 archives, which apache/doris-thirdparty's automation produces by running this very script with no package arguments. A macOS prefix carries libhdfs3 (lib64/libhdfs3.a, include/hdfs/) and nothing else.

That was correct while hadoop's native build could not complete on a Mac at all. apache/doris-thirdparty#407 fixed it, and hadoop-3.4.2.3-for-doris — selected since #66783 — carries the fix, so the 3.4 fork builds here now.

hadoop_libs, the 3.3.6 fork, stays Linux-only: it has none of those fixes, and nothing built on macOS reads its hadoop_hdfs/ prefix — the BE includes hadoop_hdfs_3_4/hdfs.h, and the cloud module, the only consumer of the 3.3.6 one, is not built on macOS.

Making the BE link hadoop's libhdfs.a on macOS instead of libhdfs3 (be/CMakeLists.txt still selects libhdfs3 there) is a separate change. It needs this one first, and it needs the published prebuilt archives rebuilt with it — which the doris-thirdparty automation does on the next thirdparty/ change, i.e. on this one.

  Verified on macOS 26.5 / arm64. With this change the default package list ends with hadoop_libs_3_4 and still contains no hadoop_libs; HADOOP_LIBS_3_4 is already unconditional in TP_ARCHIVES, so the source is downloaded on macOS today and download-thirdparty.sh needs no change. The package build itself was verified in [chore](thirdparty) upgrade HADOOP_LIBS_3_4 to hadoop-3.4.2.3-for-doris and build macOS CI on JDK 17 #66783: build-thirdparty.sh hadoop_libs_3_4 exits 0 and installs

• Behavior changed:

  • Yes. A macOS third-party build now also builds hadoop 3.4.2.3 and installs lib/hadoop_hdfs_3_4/. Linux is byte for byte unchanged.

• Does this need documentation?

  • No.
