top: add a program name to 'Ctrl' bottom window header

Browse Source 
This minor addition to that new 'Ctrl' feature is more
important than it seems. It's responsible for alerting
yours truly to the 'LIBPROC_HIDE_KERNEL' bug addressed
in the very next commit. All this while, program names
for some tasks would be mysteriously replaced with the
kernel 'kworker' names. However, customary clutter for
the top process display tended to obscure such a fact.

[ and, of course, to notice the problem in the first ]
[ place required one to have the command line toggle ]
[ 'off' or perhaps to toggle its state 'on' & 'off'. ]
