my copyright: some minor adjustments

- remove "all rights reserved" from my copyright on my extensive
  contributions
- belatedly add my name to tuning.7 which I was a large contributor to
  several years ago

This commit can also serve as implicit permission for any formatting or
non-substantive changes that FreeBSD wishes to make in the future.
