Update to 5.2.1 and fix build under NetBSD current (post 2.0D).  Also change
categories to 'misc'.  From Kibum Han in PR pkg/25642.

Changes since 5.0 include:

* When given -l and similar options, ls now adjusts the output column
  widths to fit the data, so that output lines are shorter and have
  columns that line up better.  This may adversely affect shell
  scripts that expect fixed-width columns, but such shell scripts were
  not portable anyway, even with old GNU ls where the columns became
  ragged when a datum was too wide.

* ls --width=N (for very large N) is no longer subject to an address
  arithmetic bug that could result in bounds violations.

* ls --width=N (with -x or -C) no longer allocates more space
  (potentially much more) than necessary for a given directory.
