test: s390x z15 accelerated zlib fixes

Modern s390x x15 has accelerated zlib operations on the CPU. Many
distros currently have patches to take advantage of this feature. One
side-effect of these patches is that compression routine is no longer
deterministic as with software. Interruption to input produces
different compressed results. Invalid input can result in processor
fault.
