top: let's exploit the new standardized errno handling

Browse Source 
With the library having now normalized errno handling,
perhaps it is time at least one program took advantage
of it. So, instead of printing just a message with the
programs's line number, top will now also provide that
associated errno string text, compliments of strerror.

[ with those newlib functions returning NULL, we can ]
[ use errno directly in strerror. for the ones which ]
[ yield an int, all we need do is invert such return ]
[ values before passing it to the strerror function. ]
