[DynInst_API:] new-parallel-parsing config is broken for testsuite

["Mark W. Krentel" <krentel@xxxxxxxx>]

The new-parallel-parsing branch of dyninst has this in the top-level
CMakeLists.txt.

add_subdirectory(testsuite)

But the testsuite directory is empty in the n-p-p branch.  As a
result, cmake falls over with:

-- Found dependency location /home/krentel/config/build-dyninst/dyninstAPI
CMake Error at CMakeLists.txt:73 (add_subdirectory):
  The source directory

    /home/krentel/config/dyninst/testsuite

  does not contain a CMakeLists.txt file.

Maybe somebody forgot to run git add ....
