`type: tree` creates issues in `deb` packages

What happened?

Creating a deb package containing a directory using type: tree causes issues with the package on Ubuntu.

On Ubuntu 20 and 22, opening the package with Software Install fails with the error message `Failed to install file: not supported.

On Ubuntu 24, App Center opens and installs the package without issues.

On all three Ubuntu versions, gdebi reports List of files for 'package.deb' could not be read in the Included files tab.

How can we reproduce this?

Create a directory containing a single file using mkdir directory && echo content > directory/file. Generate a deb package using the following config file

name: package
maintainer: Test
contents:
  - src: directory
    dst: /var/lib/directory
    type: tree

The package will have the issues described above. However, a package generated with the following will not

name: package
maintainer: Test
contents:
  - src: directory/file
    dst: /var/lib/directory/file

Additional context

The problem seems to come from the data.tar archive's format. The issue affects the package regardless of compression setting and decompressing and recompressing it does not solve the issue. However, extracting the tar archive and recreating it creates a working package.
