cmake: Explicitly include the CheckIncludeFiles module.

This fixes the build with CMake 3.4.0:

  CMake Error at kdbg/CMakeLists.txt:8 (CHECK_INCLUDE_FILES):
    Unknown CMake command "CHECK_INCLUDE_FILES".
  -- Configuring incomplete, errors occurred!

kdbg/CMakeLists.txt was including the CheckIncludeFiles module
indirectly via KDE's CMake files and FindThreads.cmake. This does not
work anymore as of CMake commit 9924a212 ("FindThreads: replace
CheckIncludeFiles by CheckIncludeFile").
