top: make compilation possible under netbsd-curses too

Browse Source 
Whoa, I had never considered an alternative to ncurses
until the issue referenced below was raised. Thus, I'm
surprised to find that 'tparm' was the only impediment
to ultimately utilizing this alternate curses library.

And, while we could have substituted that non-standard
'tiparm' with only 2 arguments, we'll utilize the full
parms compliment in the spirit of that original patch.

Frankly, the task of developing an alternative library
to that ncurses implementation really boggles my mind.

Congratulations to rofl0r, whoever that masked man is.
