    usbconfig.8: Improve style and fix examples
    
    - Use Ar macros for arguments
    - Stylize the argument synopsis to the -d flag
    - Change the width of the list to one of the actual tags in the list
    - Stylize "ugen" and "/dev/ugen" with Cm as those are constant strings,
      which are usually treated as command modifiers.
    - Break long lines to reduce the number of warnings from linters
    - Fix examples; the -d flag is now required when specifying the unit and
      the address with the "dot notation".
    
    MFC after:      2 weeks
    
    (cherry picked from commit 5eafaf9e68894cda4e8dca5f363be0b4f15b5cd6)
