Fix Bug 3751 configuring multiple global syslog facilities overwrites previous ones in /etc/syslog.conf

- multiple nodes configured under 'system syslog global' are appended to syslog.conf
- default '*.notice -/var/log/messages' is removed from syslog.conf if any
  node is configured under 'system syslog global' and is put back when nothing
  configured under 'system syslog global'
- syslog process only restarted once after making all changes in config
- added commit checks at 'system syslog <>' level nodes to specify facility
