[HECnet] Disallow system from dz lines (OpenVMS/VAX 7.3)

[Johnny Billquist]

And by the way, I would really just change what hours you are allowed to 
log in as local. I wouldn't start mucking about with the line attributes.

Also, I'd create a second user with SETPRV, and then you can mess up 
SYSTEM as much as you want. Then it's easy to recover with your other user.
