syslog-ng: fix syslog-ng startup problem with systemd

1. Fix syslog-ng service cannot startup after upgrade to 3.15.1

   1) Align path of syslog-ng.conf between syslog-ng@default
      and do_install in syslog-ng.inc
   2) create a default instance for syslog-ng
   3) Install default parameter file to /etc/default according
      to https://github.com/balabit/syslog-ng/commit
      /649d1151e79033cc2b81b3353917507266814436

2. Fix "Failed to acquire /run/systemd/journal/syslog socket,
   disabling systemd-syslog source;" accordint to below content
   from syslog-ng admin guide.

   1) for linux, If the host is running under systemd, syslog-ng
      OSE reads directly from the systemd journal file using the
      systemd-journal() source.
   2) If possible, use the more reliable systemd-journal() driver
      instead.
   3) The socket activation of systemd is buggy, causing some log
      messages to get lost during syst
