  sbin/devfs: clarify usage
  
  - Note existence of -m option.
  - Note that -s applies to rule keyword, only, by adding usage text
    specifically for the `rule` and `ruleset` keywords.
  
  Don't go into any further detail in usage(..) -- it's best that one
  reads the manpage to get a better idea of how things work as there are
  a number of different option-specific keywords and arguments, as well
  as some rule grammar.
