s390: remove the last remnants of cputime_t

Browse Source 
cputime_t was a core kernel type, removed by commits
ed5c8c854f2b..b672592f0221. As explained in commit b672592f02
("sched/cputime: Remove generic asm headers"), the final cleanup is for
the arch to provide cputime_to_nsec[s](). Commit e53051e757
("s390/cputime: provide archicture specific cputime_to_nsecs") did that,
but just didn't remove the then-unused cputime_to_usecs() and associated
remnants.
