Fix 698839: Add hash for testcases that fail to decode anything.

The testrunner stated that the expected hash for 042_13.jb2 and
042_14.jb2 was that of a successfully decoded image. Historically
these two images have caused jbig2dec to segfault, but nowadays
they correctly cause FATAL ERRORs. When FATAL ERRORs are
encountered as hash covering 0 bytes of image data is computed,
so the testrunner now expects this hash instead. Therefore the
check now run successfully.
