s390: remove the last remnants of cputime_t
cputime_t was a core kernel type, removed by commits ed5c8c854f2b..b672592f0221. As explained in commitb672592f02
("sched/cputime: Remove generic asm headers"), the final cleanup is for the arch to provide cputime_to_nsec[s](). Commite53051e757
("s390/cputime: provide archicture specific cputime_to_nsecs") did that, but just didn't remove the then-unused cputime_to_usecs() and associated remnants.
