getrusage: RUSAGE_THREAD should return ru_utime and ru_stime
commit 8916edef5888c5d8fe283714416a9ca95b4c3431 upstream.
Impact: task stats regression fix
Original getrusage(RUSAGE_THREAD) implementation can return ru_utime and
ru_stime. But commit "f06febc: timers: fix itimer/many thread hang" broke it.
this patch restores it.
