sched/cputime: Convert kcpustat to nsecs
commit 7fb1327ee9b92fca27662f9b9d60c7c3376d6c69 upstream.
Kernel CPU stats are stored in cputime_t which is an architecture
defined type, and hence a bit opaque and requiring accessors and mutators
for any operation.
Converting them to nsecs simplifies the code and is one step toward
the removal of cputime_t in the core code.
