    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)).
