libssh: security bump to version 0.8.4

Fixes CVE-2018-10933: authentication bypass vulnerability in the server
code. By presenting the server an SSH2_MSG_USERAUTH_SUCCESS message in
place of the SSH2_MSG_USERAUTH_REQUEST message which the server would
expect to initiate authentication, the attacker could successfully
authenticate without any credentials.
