plugin/snmp: add support for if_octets

The types used in the SNMP plugin aren't user defined, but defined in types.db.
Because of the assumption that they were user defined, the patch supplied by
Neptune Ning wasn't accepted. His patch has now been merged with this commit. A
little fallback has been added to catch types that aren't defined in our code yet.
