top: add a program name to 'Ctrl' bottom window header <=== port of newlib bad7f2a2

Browse Source 
______________________________ original newlib message

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 <=== not in this branch, cookie
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'. ]
