top: harden detailed stats two abreast summary display

When displaying detailed cpu statistics, as opposed to
those scalable graphs, only two per line can be shown.

Therefore, if we are showing a detail version, our '4'
toggle must prematurely revert to single mode display.

Conversely, the 't' toggle must also turn off that '4'
toggle rather than try to print more than 2 abreast if
we're currently executing in detailed statistics mode.
