mandos-ctl: Refactor

* mandos-ctl (commands_and_clients_from_options): Rename to
                         "commands_from_options"; all clients changed.
  (main): Get "clientnames" directly from "options.client", and move
          invocation of commands_from_options() to after "clients" is
          available.
