selftests/vDSO: fix -Wformat warning in vdso_test_correctness

Fix the following -Wformat warnings in vdso_test_correctness.c:

vdso_test_correctness.c: In function ‘test_one_clock_gettime64’:
vdso_test_correctness.c:352:21: warning: format ‘%ld’ expects argument of type ‘long int’, but argument 3 has type ‘long long int’ [-Wformat=]

The tv_sec member of __kernel_timespec is long long, both in
uapi/linux/time_types.h and locally in vdso_test_correctness.c.
