Bugfix: fix restic dump of tar file with 32-bit binary When using a 32-bit build of restic, the `restic dump` command could in some cases create tar files containing negative uid and gid. These files cannot be read by gnu tar. This corner case especially applies to backups from stdin on Windows. We have changed the dump command to create valid tar files in this case. https://github.com/restic/restic/issues/4103 https://github.com/restic/restic/pull/4104
