Synology SA3400 and SA3600 models are detected as generic linux

Hi Observium support,

The Synology SA3400 and SA3600 devices are not obtaining correct OS matching when they are discovered. I was get this to work by modifying the modelName.0 string match found in the following file:

includes/definitions/os/synology.inc.php file.

Please review the diff below and hopefully apply this permanently. I think it will make life easier for users in the future.
