unittest: Fix and enable applybox_test

[stweil]

It needs an update of the test submodule.

The tests only pass with a small modification of the ground truth texts
(kTruthTextWords, kTruthTextLine).

unittest/Makefile.am needs slight change for the test to build - needs leptonica.

applybox_test_LDADD = $(GTEST_LIBS) $(TESS_LIBS) $(LEPTONICA_LIBS)

Error was:

Yes, that's correct. I missed that dependency because my build with configure --disable-shared worked fine. Without --disable-shared, I get the linker error.
