Subject: [PATCH] Fix: Bundle lz4 in macOS JNI builds

The macos-15 runner image now ships a Homebrew lz4 that includes a
CMake config, so the JNI build linked the shared liblz4.dylib and the
dependency check rejected libarrow_dataset_jni.dylib. Build lz4 from
source with -Dlz4_SOURCE=BUNDLED so it is always linked statically.
