check-host-tar.sh: blacklist tar 1.30+

Browse source 
Tar 1.30 changed the --numeric-owner output for filenames > 100 characters,
leading to hash mismatches for the tar archives we create ourselves from
git.  This is really a fix for a bug in earlier tar versions regarding
deterministic output, so it is unlikely to be reverted in later versions.

For more details, see:
http://lists.busybox.net/pipermail/buildroot/2018-January/211222.html

To work around this issue, blacklist tar 1.30+ similar to how we do it for
pre-1.17 versions so Buildroot falls back to building host-tar.
