sched/cpuacct: Avoid %lld seq_printf warning

For s390 kernel builds I keep getting this warning:

 kernel/sched/cpuacct.c: In function 'cpuacct_stats_show':
 kernel/sched/cpuacct.c:298:25: warning: format '%lld' expects argument of type 'long long int', but argument 4 has type 'clock_t {aka long int}' [-Wformat=]
   seq_printf(sf, "%s %lld\n",

Silence the warning by adding an explicit cast.
