Fix memory leak in H5LTopen_file_image when H5LT_FILE_IMAGE_DONT_COPY flag is used (#4021)
When the H5LT_FILE_IMAGE_DONT_COPY flag is passed to H5LTopen_file_image, the internally-allocated
udata structure gets leaked as the core file driver doesn't have a way to determine when or if it
needs to call the 'udata_free' callback. This has been fixed by freeing the udata structure when
the 'image_free' callback gets made during file close, where the file is holding the last reference
to the udata structure.
