    racct: Fix accounting of CPU time for the system idle process

    - Add a flag which cleanly indicates that a given process is the system
      idle process.
    - Modify racctd() to skip over the idle proc when aggregating CPU time
      and other metrics which don't apply to the idle thread.
    - Remove handling for idle threads from racct_getpcpu().
