[PATCH 3/7] selftests: vDSO: vdso_test_correctness: Fix -Wold-style-definitions

[Thomas Weißschuh]

Functions definitions without any argument list produce a warning with
-Wold-style-definition:

vdso_test_correctness.c:111:13: warning: old-style function definition 
[-Wold-style-definition]
  111 | static void fill_function_pointers()
      |             ^~~~~~~~~~~~~~~~~~~~~~

Explicitly use an empty argument list.
