refactor(pkg test): Avoid gzip on tarballs

This avoids gzipping the tarballs that are created to test end to end
functionality. Compressing and decompressing them takes time for minimal
space saving so this PR just removes it.

It retains the compression in the tarballs test, to make sure compressed
tarballs continue to work.
