Fix bioformats2raw tool

[kostrykin]

bioformats2raw was producing blank outputs on Galaxy EU but running fine locally and in CI.

The issue boiled down to a known Java issue with NFS volumes: https://issues.apache.org/jira/browse/KAFKA-6647

The fix is to redirect temporary output to a directory within the Docker container.

Much thanks to @bgruening for hunting down this bug! 🎉 🎉

@bugraoezdemir This label seems a bit unspecific. Can we change this to be more expressive?
