[pbs-devel] [PATCH v3 many] fix #4995: Include symlinks in zip file restore

[Filip Schauer <f.schauer@proxmox.com>]

Include symlinks when restoring files from a backup as a zip file.

Resulting ZIP files were successfully tested on Linux with: zipinfo,
unzip, unar

On Windows the extracted symlinks show up as regular files containing
the path to the destination. As far as I am aware Windows Explorer does
not support symlinks in ZIP files.

Changes since v2:
* Add a FileType enum and embed the symlink target into the enum.
* Add unit tests for ZipEncoder to the proxmox-compression crate

Changes since v1:
* Use P instead of &Path
* Fix compile error due to misplaced comma
* Check content before symlink_target, since regular files are more
  common than symlinks
