Fix kafka setup scripts

Browse source 
This commit updates the kafka setup scripts to ensure that the kafka setup is clean between builds, by
setting an explicit zookeeper data directory to be cleaned each time, and correctly overriding `log.dirs`
instead of `log.dir` to ensure that the kafka logs are written and wiped in a consistent place each time,
which helps when using the non-immutable images used in arm64 tests.
