1-second resolution of process accounting times

[H. Morrow Long [Systems Center]]

	We noticed this change in 4.2bsd very quickly after conversion
	from 4.1bsd. We had ported the System III accounting package to
	4.1bsd.  We noticed that under 4.2bsd many of the totals for
	CPU usage were coming up zero for normal users.

	We then were able to attribute it to the coarse time
	measurement being used under 4.2bsd (seconds) and the fact
	that many of the 'average' processes on a system never use at
	least one second of cpu time and therefore show up with zero
	time.

	We modified the accounting routines in sys/kern_acct.c to
	provide utime, stime and etime in 60ths of a second (the 4.1bsd
	way) rather than seconds.
