indoorgml schema patch/test broken

The patch for indoorgmlnavi.xsd appears to be outdated and breaks the build:

https://github.com/highsource/ogc-schemas/blob/master/schemas/src/main/patches/ogc.patch#L252-L263

Removing that section of ogc.patch allows the build to progress until the scripts tests, where this test fails:

[scripts/tests/IndoorGML/1.0/FJK-Haus_IndoorGML_withEXR-corrected.xml](https://github.com/highsource/ogc-schemas/blob/master/scripts/tests/IndoorGML/1.0/FJK-Haus_IndoorGML_withEXR-corrected.xml)

Specifically the test encounters the following error:

```
Error: Element [{http://www.opengis.net/indoorgml/1.0/core}Geometry3D] could not be unmarshalled as is not known in this context and the property does not allow DOM content.
```
