ldomctl: Omit tty device from status output

[Klemens Nanni]

Now that `ldomctl console ...' is implemented there is actually no need
to print the device any longer, it is an implementation detail that
should be hidden just like it is the case with vmctl.

That also makes it fit nicely on serial consoles again.

        $ doas ldomctl status primary
        primary          -        running          OpenBSD running              
      1%
        $ jot -s '' -b . 72
        ........................................................................
        $ doas obj/ldomctl status primary
        primary          running          OpenBSD running                    0%

OK?
