Fixup extaction paths for rdsquashfs on Windows
- If we generate a manifest file, use the fix-path function to produce a fixed up, actual name as the source path. - When unpacking, create files for the fixed up, actual name. There is no need to touch gensquashfs, if the manifest file is used to re-pack the stuff, the original paths are used and the files are source from the fixed-up paths.
