sched: accounting regression since rc1
Fix the accounting regression for CONFIG_VIRT_CPU_ACCOUNTING. It
reverts parts of commit b27f03d4bdc145a09fb7b0c0e004b29f1ee555fa by
converting fs/proc/array.c back to cputime_t. The new functions
task_utime and task_stime now return cputime_t instead of clock_t. If
CONFIG_VIRT_CPU_ACCOUTING is set, task->utime and task->stime are
returned directly instead of using sum_exec_runtime.
Patch is tested on s390x with and without VIRT_CPU_ACCOUTING as well as
on i386.
