mini_snmpd: Add sysDescr option.

Some monitoring tools will run into errors when sysDescr field is empty. This was the case for cacti 1.2.8 that i'm using to monitor my network. Ideally the sysDescr field would contain some information from the overview of luci, e.g. the Model, Firmware and Kernel-Version fields, but i am stranger to OpenWRT, so I'm unable to do that.
