config: remove /dev/console bind mount

The code in conf will bind-mount a /dev/pts/<n> device over a dummy regular
/dev/console file. If users really want /dev/console bind-mount from the host
they can request it explicitly in the containers config file. This change will
have no effect on current LX{C,D} behavior since we (as said above) overmount
the /dev/console bind-mount anyway.
