description:
boot.cfg.5: Note that userconf can be used multiple times

Additionally:
- Make it easier for the reader to learn which keywords can be used
  multiple times
- Use multiple "userconf" lines in the EXAMPLES section, conveniently
  listing the current DRM drivers that a user might need to disable to
  troubleshoot "blank screen after boot" issues.
