Fix container build logging

In Quarkus 2.10.CR1, the container build (e.g. Docker) performed by Quarkus does not log any output anymore. This appears to be caused by the refactoring in commit 418d986, as the `Runnable#run()` method is never called in `ExecUtil#exec()` on the `Runnable` returned by `outputFilterFunction`.
