Peter Korsgaard f1ee7015a4 support/dependencies/check-host-tar.sh: blacklist tar 1.35+
GNU tar 1.35 changed the behaviour for the devmajor/devminor fields,
breaking the download hash validation.  For details, see:

https://lists.gnu.org/archive/html/info-gnu/2023-07/msg00005.html
https://patchwork.ozlabs.org/project/buildroot/patch/20231018141155.533944-1-vfazio@gmail.com/

To work around this issue, blacklist tar 1.35+ similar to how we do it for
pre-1.27 versions so Buildroot falls back to building host-tar (which is
currently 1.34).
