test_bytestream (C++, Java): Byte-compare source w/ destination; Java: Add FileUtil mapping jau::fs::file_util.hpp functionality

- FileUtil.compare() is covered via TestByteStream01
- Not mapped:
  - dir_item
  - fmode_t
  - file_stats

TODO
- Test CopyOptions and TraverseOptions
- Partially copy test_fileutils01.cpp and testsudo_fileutils02.cpp
  - copy()
  - remove()
  - mount_image()
