  Make TIOCCONS use priv_check() instead of checking /dev/console permissions.
  
  As discussed with Robert on IRC, checking the permissions on
  /dev/console to see if we can call TIOCCONS could be unreliable. When we
  run a chroot() without a devfs instance mounted inside, it won't
  actually check the permissions on the device node inside the devfs
  instance.
  
  Using the already existing PRIV_TTY_CONSOLE for this seems like a better
  idea.
