Fix the accounting regression for CONFIG_VIRT_CPU_ACCOUNTING. It reverts parts of commit b27f03d4 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.
