userspace: trivial fixes to wrs_status_led 

  - fix option parsing, and a comment about terse/quiet and verbose
  - added -o (range) and -g (reen). Documented -y (ellow).
  - renamed prgname to pgrname ("prg" like "prog"), as we have 86 of
    them and only 2 pgrname in wrs_version, which was a typo I fear.
