docs: clean up dmesg.1 manual

* Add lightness to synopsis.
* Add few missing italic highlights to text segments which refer
  command line argument(s).
* Turn off bold where ever possible (makes text unnecessarily heavy).
* Add spaces after dots (English spacing).
* Use URL and email macros where appropriate.
