Many tests have preconditions like a correct version of the test submodule
or installed traineddata files at the right location. They fail or even
crash if those preconditions are not met.
The latest version of Googletest supports skipping single tests with
GTEST_SKIP which is used here to skip tests in applybox_test when
tessdata/eng.traineddata is missing.

It needs an update of the test submodule.
The tests only pass with a small modification of the ground truth texts
(kTruthTextWords, kTruthTextLine).
