selftests: vDSO: vdso_config: Avoid -Wunused-variables

Not all users of this header make use of all its variables.
For example vdso_test_correctness.c does not use "versions":

In file included from vdso_test_correctness.c:22:
vdso_config.h:61:20: warning: ‘versions’ defined but not used [-Wunused-variable]
   61 | static const char *versions[7] = {
      |                    ^~~~~~~~

Avoid those warnings through attribute((unused)).
