PUT /containers/{id}/archive behaves differently to docker.

Issue Description

I have an application that populates volume content by creating a tar stream and sending it to a container with a mounted volume.

With docker I can mount a volume to /mymount and have the tar contain /mymount/folder/file and use the path / with the PUT request and the volume is populated as expected. With podman the volume remains empty (although the request does return 200), unless I alter the tar to contain folder/file and use the path /mymount with the PUT request.

Steps to reproduce the issue

Steps to reproduce the issue

1. Create tarfile with absolute paths that include the volume mount point
2. Send the tarfile as a PUT request to the /containers/{id}/archive endpoint for a container with a new volume mounted at the volume mount point
3. Verify the volume content

Describe the results you received

The volume remains empty

Describe the results you expected

The volume should contain the files from the tar (eg /mymount/myfile or /mymount/mydir/myfile)
