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.

Fix 306 warnings from MS C:
tesseract\ccutil\unicharset.h(242): warning C4267:
'argument': conversion from 'size_t' to 'int', possible loss of data
The change also avoids some type conversions.
The related code in training/util.h now uses the GOOGLE_TESSERACT macro
to enable Google specific code to disable heap checking.
