Fix encoding for native images

[Schaka]

Currently, native images don't encode file paths properly.
This is because sun.jnu.encoding is not passed correctly at build time by the looks of it.

There's a ticket over at paketo's buildpack: paketo-buildpacks/native-image#344
Additionally, someone documented this behavior with vanilla GraalVM: https://gist.github.com/volgar1x/3b27360eac7b989c167bf7d548135f9c

By the looks of it, this seems to be a bug in the way paketo buildpacks build the image.
If I cannot get a sufficient response from the GraalVM team over at Oracle, I may need to create and manage my own buildpack or switch over to Kotlin Path API which seems to at least somewhat work

This is temporarily fixed with a hacky workaround
