find: improve readability of --help output

* find/util.c (usage): Start sentences with upper case.
Add extra newlines to put each section (operators, options, tests, and
actions) on its own line.
Move the typical generic options --help and --version to the end.
* NEWS (Documentation Changes): Mention the change.
