[PATCH cgroup/for-4.15] sched/cputime: Add dummy cputime_adjust() implementation for CONFIG_VIRT_CPU_ACCOUNTING_NATIVE

Hello,

Another follow-up fix. I missed a dummy implementation leading to
bulid failure on s390. Because the bug and fix are trivial, I
directly applied the patch to cgroup/for-4.15. Please let me know if
it should be routed differently.

Thanks.
