sched/cputime: Add kcpustat_field_total helper
Provide a new helper function which sums up a given type of cpustat
over a specified cpumask.
This allows the caller's code to be simpler and avoids duplication.
For example, subsequent patch in the steal governor use this exact
same pattern when calculating steal time.
Number of cpus can be derived from cpumask_weight() where necessary.
