Those fixed fields come from the KML structure itself and are exposed as OGR 
fields because it is convenient in some contexts. AFAICS there's no easy way of 
not exposing them. So you will likely have to do some scripting to list the 
available fields, remove the ones you don't want too, and build a SQL statement 
or use -select to select just the ones you're interested into.
