[RFC PATCH 2/2] doc: remove dated info and refs to sample hooks

[Kenneth Lorber <keni@his.com>]

In the glossary entry for hooks:
- don't discuss renaming the sample hooks
- don't discuss the need to make the sample hooks executable as the existing
  wording is too specific: it implies only the sample hooks need to be executable
  and the need to make scripts executable is already discussed near the top of hooks(5).
