bin: allow specifying the console on the command line

As in:

    $ vtcol --console /dev/tty6 colors get
    solarized
    $ vtcol --console /dev/tty6 colors set phosphor
    $ vtcol --console /dev/tty6 colors get
    phosphor

That simplifies testing so much I wonder why the heck I needed
this long to finally implement it.
