selftests: vDSO: vdso_test_correctness: Fix -Wstrict-prototypes 



Functions definitions without any argument list produce a warning with
-Wstrict-prototypes:

vdso_test_correctness.c:111:13: warning: function declaration isn’t a prototype [-Wstrict-prototypes]
  111 | static void fill_function_pointers()
      |             ^~~~~~~~~~~~~~~~~~~~~~

Explicitly use an empty argument list.

Now that all selftests a free of this warning, enable it in the Makefile.
