selftests/vDSO: fix building errors on LoongArch

Patch series "selftests/vDSO: Fix errors on LoongArch", v4.


This patch (of 2):

There exist the following errors when build vDSO selftests on LoongArch:

  # make headers && cd tools/testing/selftests/vDSO && make
  ...
  error: 'VDSO_VERSION' undeclared (first use in this function)
  ...
  error: 'VDSO_NAMES' undeclared (first use in this function)

We can see the following code in arch/loongarch/vdso/vdso.lds.S:

VERSION
{
        LINUX_5.10 {
        global:
                __vdso_getcpu;
                __vdso_clock_getres;
                __vdso_clock_gettime;
                __vdso_gettimeofday;
                __vdso_rt_sigreturn;
        local: *;
        };
}

so VDSO_VERSION should be 6 and VDSO_NAMES should be 1 for LoongArch,
add them to fix the building errors on LoongArch.
