5b976bfb55 fix langdata (user words/patterns) file suffixes for LSTMs: 
- add another constructor for LSTMRecognizer
  which takes the language_data_path_prefix configured/selected
  at runtime and passes it to the internal CCUtil
- use this in Tesseract::init_tesseract_lang_data when LSTMs
  are available
