Fix rtsold's usage message

- Remove -a from the usage message example dealing with specific
  interfaces. -a only makes sense when not specifying an interface,
  such that it's to be run on all interfaces
- Fix the pidfile option (it's -p, not -P)
- Change `interfaces` to `interface` to match the manpage
