systat: use and correctly display 64bit counters.

Browse Source 
Following struct vmtotal changes, make systat use and correctly
display 64-bit counters.  Switch to humanize_number(3) to overcome
homegrown arithmetics limits in pretty printing large numbers.  Use
1024 as a divisor for memory fields to make it consistent with other
tools and users expectations.
