Fix tests on linux in upload_all_java_tools.sh

Tempoarily workaround #20753 to unblock bazelbuild/java_tools#87

Setting `--sandbox_tmpfs_path=/tmp` for linux matches [the current behavior of bazelci.py](https://github.com/bazelbuild/continuous-integration/blob/7a8d90d15520b81e0f330a85772c5416a04d0061/buildkite/bazelci.py#L1976)
