logwatch: Fixes bug13762 - ssh logins not shown on Log Summary page

- Due to the update of openssh to version 9.8 in CU187, logwatch no longer found the sshd
   login data from the messages log as the daemon was changed to sshd-session.
- Therefore the daily logwatch files were missing the sshd information in them.
- A patch to add support for openssh-9.8 sshd-session and port info has been merged into
   the logwatch git system and will be included into the next released version of logwatch
- Update logwatch from version 7.8 to 7.11 and add patch for openssh-9.8 support.
- Update the previous three logwatch patches for version 7.11
- Tested on my vm testbed. Confirmed that logwatch now includes back the sshd information
   into the Log Summary page.
- When logwatch is updated to version 7.12 then the openssh-9.8 support patch will be able
   to be removed.
