Update unittest for new script data location and fix out-of-tree build (

#1386) tessdata_best and tessdata_fast recently changed the path for script data, so the tests have to be updated, too. In addition, the relative paths did not work with out-of-tree builds. Use absolute paths and add them as C macros to the compiler flags. Signed-off-by: Stefan Weil <sw@weilnetz.de>
