Add openssh-8.1p1-use-openssl-kdf.patch (jsc#SLE-9443). This performs key derivation using OpenSSL's SSHKDF facility, which allows OpenSSH to benefit from the former's FIPS certification status. Make sure ssh-keygen runs if SSHD_AUTO_KEYGEN variable is unset or contains an unrecognized value (bsc#1157176).

There are following changes in default settings of ssh client and server: * Accepting and sending of locale environment variables in protocol 2 is enabled. * PAM authentication is enabled and mostly even required, do not turn it off. * root authentiation with password is enabled by default (PermitRootLogin yes). NOTE: this has security implications and is only done in order to not change behaviour of the server in an update. We strongly suggest setting this option either "prohibit-password" or even better to "no" (which disables direct remote root login entirely). * DSA authentication is enabled by default for maximum compatibility. NOTE: do not use DSA authentication since it is being phased out for a reason - the size of DSA keys is limited by the standard to 1024 bits which cannot be considered safe any more. * Accepting all RFC4419 specified DH group parameters. See KexDHMin in ssh_config and sshd_config manual pages. For more information on differences in SUSE OpenSSH package see README.FIPS
