README: use 'restrict' option in authorized_keys(5) snippet.
This is shorter and more future-proof. Quoting the manual:
restrict
Enable all restrictions, i.e. disable port, agent and X11
forwarding, as well as disabling PTY allocation and execution of
~/.ssh/rc. If any future restriction capabilities are added to
authorized_keys files they will be included in this set.
Note that this won't work with Jessie's OpenSSH server.
