Fredrik Fornwall 2b61e3a317 openssh: Replace some link(2) with rename(2)
OpenSSH uses a link to take a backup while replacing the known_hosts
file:

(1) link known_hosts to known_hosts.old
(2) move new file to known_hosts (overwriting the link there)

Since links are not allowed we replace link with rename:

(1) rename known_hosts to known_hosts.old
(2) move new file to known_hosts

This means that there is a window between (1) and (2) where the
known_hosts file is not available, but that is a really short window
and is hopefully acceptable here.

Fixes #2909.
