top: adapt for loss of fields obsoleted with linux 2.6

Browse Source 
It would have been nice to remove this 'nDRT' guy from
the fields management screen and man document as well.
But, while this version of top could be made to handle
an older rcfile, the reverse would not have been true.

Besides, it's been zero for so long already we'll just
include a 'deprecated' note in top's man page for now.

[ the 'nTH ' field number was corrected in there too ]
