freebsd-update.conf.5: Address style issues

- Do not set Os to FreeBSD explicitly. We don't do it in other manual
  pages.
- Remove macros from the -width specifier.
- Use Xr instead of Cm to refer to the freebsd-update command.
- Address some mandoc lint warnings and use \(em instead of --.
- Wordsmith some paragraphs.
- Add a missing El macro.

MFC after:	1 week
