This change should probably be in 2.1, but I'm not sure if it breaks
anything. pcvt has restricted i// privilege to root for a long time.
i/o privilege should never have been granted in devices other than
/dev/io. /dev/io has its own permissions which can be used to grant
i/o privilege to a more selective group than root || { anyone that
can talk to a ttyv }.
i/o privilege should not be granted if kern.securelevel >= 1.
