openssh: Update to 7.8p1

openssh: Update to 7.8p1

For details see:
http://ftp.openbsd.org/pub/OpenBSD/OpenSSH/portable/ChangeLog

I didn't find an official lfs-patch for openssl-1.1-compatibility,
so I used the patch from here:
https://git.archlinux.org/svntogit/packages.git/plain/trunk/openssl-1.1.0.patch?h=packages/openssh

Building ran without any errors.

I tested with both machines (test on Core 120 - and productive - on Core 122) and found no errors so far:

...
[root@ipfiretest ~]# ssh -V
OpenSSH_7.8p1, OpenSSL 1.1.0h  27 Mar 2018
...

...
root@ipfire: / # ssh -V
OpenSSH_7.8p1, OpenSSL 1.1.0h  27 Mar 2018
...

All ssh-connections ran fine but I'm not REALLY sure if this is sufficient for anyone else.

Could someone please check and confirm!?

Best,
Matthias
