sched/cputime: Fix IA64 build error of missing arch_vtime_task_switch() prototype

The following commit:

  c89970202a11 ("cputime: remove cputime_to_nsecs fallback")

Removed an <asm/cputime.h> inclusion from <linux/sched/cputime.h>, but this
broke the IA64 build:

    arch/ia64/kernel/time.c:110:6: warning: no previous prototype for 'arch_vtime_task_switch' [-Wmissing-prototypes]

Add in the missing <asm/cputime.h> header to fix it.
