Current Rust build fails with Cargo installed

[RichardWarburton]

If I run the current gradle build then it fails for me. I'm using windows to run the build and have cargo installed. I've tried both using ./gradlew under mingw git bash and also gradlew.bat under regular windows cmd.exe here is the output from the shell related to cargo if I pass the --debug flag:

If I run ./gradlew -x "runRustCarExample" then I the RustGeneratorTest fails for me.

Seems that currently, the Rust build has sprung up as failing again after latest commits.

I've added a property sbe.skipRust that can be used to skip the Rust integration tests when cargo is found, but the tests should be skipped.
