Luca Bacci 8264b13737 tests/cxx: Do not assume that NULL is a pointer type starting with C++11
Many toolchain did not change the definition of NULL to avoid introducing
breaking changes in existing codebases. For example, on Windows NULL is
0 (int) regardless of the C++ standard in use.

Fixes the following warnings on CLang when compiling for Windows:

  ../glib/glib/tests/cxx.cpp:539:34: warning: missing sentinel in function call [-Wsentinel]
    g_test_init (&argc, &argv, NULL);
                                   ^
                                   , nullptr
  ../glib/glib/gtestutils.h:298:9: note: function has been explicitly marked sentinel here
  void    g_test_init                     (int            *argc,
          ^
