[fdo-internals] Disable GEOS support explicitly

If you remove GEOS from the OGR Provider, it will perform all 
intersection checks as BBOX overlap only.
This will cause bad behavior with both selection and tooltip.

This can be fixed by using the FDO geometry operations instead of the 
OGR which rely on GEOS.
