A fix from another pull request

A new special `ManglingFileSystemProvider` is introduces. It is used as `java.nio.file.spi.DefaultFileSystemProvider` in the new tests. This file system alters file names and file contents, which helps to ensure that operations with `java.io.File` actually use `java.nio.file.FileSystem` inside.
