update_engine: Change the default chunk_size to 200MB
cros_generate_update_payload can fail generating deltas for images
containing very large (2GB) files. To work around this, we can set a
smaller default chunk size.
On standard Chrome OS builds, the largest single file is the Chrome
browser binary, weighing in at 130MB. So this change should not affect
those builds at all.
