[Buildroot] [PATCH 8/9 v2] support/dependencies: drop check for maximal tar version

So far, we checked that the tar present on the host was at most tar
1.29, because tar 1.30 changed the way it generates archives.

Having a maximum tar version requirement meant that we would eventually
always have to build our own host-tar, as distributions are updating
the version they use.

But now, we have found a way to generate reproducible archives starting
with tar 1.27 onward, so we no longer need the check for a maximum tar
version, so we can drop that requirement.
