Don't set page segmentation mode for hocr, pdf and tsv configs

Setting the page segmentation mode in those config files gives unexpected results: the text recognized when no config or only txt is given changes if both txt and any of hocr, pdf or tsv is chosen. In a test set of nearly 200 pages from historical books, using segmentation mode 1 is typically slightly better than the default, but there are also cases where it is much worse. Therefore the user should be able to decide which page segmentation mode is best. Old results for hocr, pdf or tsv now need an explicit `--psm 1` for reproduction.
