SFTP - FileListSelection, support path transformation for host running OpenSSH on Windows

Current Situation

• when a file list file contains entries with a leading slash as e.g. /C:/tmp/file1.txt, processing is aborted with the following error:

  • error while reading 'C:/YADE/my_list.txt': java.nio.file.InvalidPathException: Illegal char <:> at index 2: /C:/tmp/file1.txt (Illegal char <:> at index 2: /C:/tmp/file1.txt)

Desired Behaviour

• The processing of the file list entries with the openSSH specific file path should work correctly.

Test Instructions

• Use the OpenSSH server on Windows.
• Create a file list file with entries with a leading slash, e.g.:
  • C:/YADE/my_list.txt

    /C:/tmp/file1.txt
    /C:/tmp/file2.txt

• Use an YADE configuration with the operation Copy and SourceFileOptions/Selection/FileListSelection/FileList=C:/YADE/my_list.txt
