openssh: stop installing symlinks to /etc/natinst/share
openssh: stop installing symlinks to /etc/natinst/share

We have been storing the openssh configuration in the configfs (under
/etc/natinst/share) so that it is shared between runmode and safemode.
Both safemode and the configfs are going away so symlinking these files
is no longer productive.
