OpenSSH-4.6p1 "set up proper environment" needs to be done as root

[Guy Hylton]

The first part of the installation, "necessary to set up the proper environment" has to be done as root.

install -v -m700 -d /var/lib/sshd &&
chown -v root:sys /var/lib/sshd &&
groupadd -g 50 sshd &&
useradd -c 'sshd PrivSep' -d /var/lib/sshd -g sshd \
    -s /bin/false -u 50 sshd

Added a note to run the commands as the root user. Thanks for the report.
