[fix](compile) auto-regenerate hadoop-deps/lib when missing due to Ma…

[hello-stephen]

…ven cache

Problem:

• When Maven build cache is hit, the dependency:copy-dependencies plugin
  execution is skipped
• This causes target/lib directory to be missing in hadoop-deps module
• Results in an incomplete BE output package without Hadoop dependencies

Solution:

• Add automatic regeneration logic in build.sh copy phase
• When lib directory is missing and BUILD_BE_JAVA_EXTENSIONS=1,
  execute 'mvn dependency:copy-dependencies' to regenerate it
• Preserves Maven cache benefits while ensuring complete output

Impact:

• Fixes intermittent missing hadoop_hdfs jars in BE output
• No impact on normal build flow (only triggers when needed)
• Maintains build cache acceleration for other plugins
