Fix the double counting of the last process thread td_incruntime
on exit, that is done once in thread_exit() and the second time in
proc_reap(), by clearing td_incruntime.

Use the opportunity to revert to the pre-RUSAGE_THREAD exporting of ruxagg()
instead of ruxagg_locked() and use it from thread_exit().
