There exist the following errors when build vDSO selftests on LoongArch:
# 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 that VDSO_VERSION should be LINUX_5.10 and VDSO_NAMES should be 1 for LoongArch in arch/loongarch/vdso/vdso.lds.S, add them to support LoongArch.
