[KillTheDoctor/CMake] Add missing keyword PRIVATE in target_link_libraries

Add PRIVATE keyword in target_link_libraries to prevent CMake Error on Windows.

While trying to compile llvm/clang on Windows, the following CMake error occurred. The reason is a missing PUBLIC/PRIVATE/INTERFACE keyword in target_link_libraries.

`
CMake Error at utils/KillTheDoctor/CMakeLists.txt:5 (target_link_libraries):
  The keyword signature for target_link_libraries has already been used with
  the target "KillTheDoctor".  All uses of target_link_libraries with a
  target must be either all-keyword or all-plain.

  The uses of the keyword signature are here:

   * cmake/modules/AddLLVM.cmake:771 (target_link_libraries)
