[syslog-ng] Regex Solaris from Linux hosts in Syslog-ng config file

If all of the solaris hosts log to a different port or IP address, then there is no need to place hosts into the syslog configuration file.
Every log message sent to the special IP/port is assumed to be from a solaris host. Then you just store them into a destination of your choosing.
