Cannot run Scala-cli with sudo

[WojciechMazur]

In the case of trying to run sudo scala-cli MyApp.scala we get a large list of warnings and the build fails to connect with Bloop. On subsequent runs, we get different outputs.
From this point, next runs without sudo privilege would also fail until we would run scala-cli clean MyApp.scala

Context: MyApp.scala is at this point a simple HelloWorld app using Scala 3.1, however, in my goal I need to have sudo privillage in order to collect CPU energy consumption measurements using the jRAPL library and it's JNI interface.

I confirm #573 fixes that locally. Maybe we should add a non-regression test for it.
