[PATCH v2 2/4] rpc: replacing ssh_is_server_known() by ssh_session_is_known_server().

[Julio Faracco <jcfaracco@xxxxxxxxx>]

After version 0.8.0, libssh deprecated the function scope
ssh_is_server_known() and moved to ssh_session_is_known_server().
So, libvirt is failing to compile using this new function name.
