openssh: upgrade 9.6p1 -> 9.7p1

0001-systemd-Add-optional-support-for-systemd-sd_notify.patch
refresh for 9.7p1

Changelog:
============
New features
------------
 * ssh(1), sshd(8): add a "global" ChannelTimeout type that watches
   all open channels and will close all open channels if there is no
   traffic on any of them for the specified interval. This is in
   addition to the existing per-channel timeouts added recently.
 * All: make DSA key support compile-time optional, defaulting to on.

Bugfixes
--------
 * sshd(8): don't append an unnecessary space to the end of subsystem
   arguments
 * ssh(1): fix the multiplexing "channel proxy" mode, broken when
   keystroke timing obfuscation was added.
 * ssh(1), sshd(8): fix spurious configuration parsing errors when
   options that accept array arguments are overridden
 * ssh-agent(1): fix potential spin in signal handler
 * Many fixes to manual pages and other documentation
 * Greatly improve interop testing against PuTTY.
