[PATCH] logwatch: Adjust the syslogd and dhcpd services to fix firewall summary

[Adolf Belka]

- In the IPFire firewall summary that is shown on a daily basis, there are lines included
   from syslod and dhcpd that are not needed to be shown.
- With syslogd every time a restart is carried out there are also lines related to the
   socket removal, creation & opening for port 514. These lines were always being shown
   as ***Unmatched entries***. This patch now filters them and does not display them when
   the restart is shown.
- With dhcpd there were a lot of execute_statement_argv[x] entries being shown as
   ***Unknown Entries***. These are not needed to be shown as the process already shows
   dhcp lease requests. This patch now filters them and does not display them.
- This has been done via a patch of the source tarball rather than copying the files
   into /usr/share/logwatch/scripts/services/ or /etc/logwatch/scripts/services/. Both
   of these approaches would mean that any updates of the service file from the logwatch
   developers would not end up being used as they would be overwritten. The patch only
   adds the changes into the provided logwatch service files, so any improvements will
   be included in any updates.
