Log:
  Fix integer truncation in affecting systat -ifstat
  
  The "systat -ifstat" command was using a u_int to store byte counters.
  With a 10Gbps or faster interface, this overflows within the default
  5 second refresh period.  Switch to using a uint64_t across the board,
  which matches the size used for all counters as of r263102.
