Jim Warner 77abe18d01 top: revert %CPU and %MEM precision to former defaults
When summary & task area memory scaling was introduced
in release 3.3.6, the percentage columns were expanded
to provide 3 decimal places of precision. In hindsight
that may have been overkill, making those columns more
of a distraction than useful, with just too much info.

This patch will revert those columns to the former one
decimal place. And as was true, that decimal point may
be sacrificed depending on the number of cpus present.

And, in case anyone might prefer additional precision,
a build option can provide it (--enable-wide-percent).
