Telemetry config generated on Linux platforms does not work on non-Linux platforms on 4.0

If you use `foundations`' built-in telemetry settings to generate your application config, the memory profiler options are only included if the package is built for Linux. This didn't previously cause issues, but since 4.0 made it an error to include unknown config fields, running the service on non-Linux OSes such as macOS cause these configs to error.

Given that common development workflows may involve a mix of running an application on Docker and natively on e.g. macOS, it would probably be better if these options were just ignored when not applicable; potentially with a warning message indicating they have no effect.
