Instead of relying on env variables for setting the ZSTD compression
configuration we can simply do what we do for IB, SDK and the rest and
use tar -I to pass "zstd -T0 --ultra -20" directly.
This makes it rather clear what is being done and allows to drop the
zstd CLI max level override as its usually capped at level 19.
