Fix tar extraction issues when running as rootHEADmaster

Following up on 20b48ed9e311c529dcce46b31ed0d986ed7e3ed4 "Fix check-if-root for
github.com/flathub-infra/vorarbeiter", the next issue those new github actions
based flathub test builds run into is

> tar: configure: Cannot change ownership to uid 1000, gid 1000: Invalid argument

etc. from the various UnpackedTarball targets.  The reason is that at least GNU
tar 1.35 defaults to --same-owner when run as root.  I hope the --no-same-owner
countermeasure is available on all the GNU and BSD tar versions that we care
about (it is at least supported by /usr/bin/tar bsdtar 3.5.3 on macOS Sequoia
15.4.1).
