top: eliminate that 'TOG4_NOTRUNC' compile conditional

When 2 abreast cpu display was introduced, the minimum
screen width was 160 columns so as to avoid (minimize)
truncation. Later that was reduced to 80 columns while
keeping the original minimum as a compile conditional.

In preparation for (virtually) eliminating these width
restrictions in a future patch this #define's history.
