Hohum. Our buildbot worker vm got upgraded to a z15. Which has zlib
deflate instructions. Which valgrind doesn't support, causing:

gnu compressed kmods are unstripped

Luckily upstream valgrind already has a patch. But that will need to be
backported and then a new package should be installed on the s390x
buildbot worker.
