Bump protobuf-gradle-plugin to 0.8.5

The version bump happened in some places already, but many references
were missed.

This fixes the following warning that shows up with newer versions of
Gradle:
> Using TaskInputs.file() with something that doesn't resolve to a File
> object has been deprecated and is scheduled to be removed in Gradle
> 5.0. Use TaskInputs.files() instead.
