ARROW-9701: [CI][Java] Add a job for s390x Java on TravisCI

[kiszk]

This PR adds a new test job for big-endian Java environment to TravisCI. It still keeps as

   allow_failures:
     - arch: s390x

[github-actions]

https://issues.apache.org/jira/browse/ARROW-9701

[kou]

This is needless because we don't use Ubuntu based docker image.

[kou]

This is needless because ARCH is already passed as environment variable.

[kou]

How about using a common script for all jobs like the following?

Generally, $(...) is preferred than `...`:

[kiszk]

@kou Thank you. Now, a TravisCI job is finished correctly with many failures. Could you review this again?

[kou]

Can we remove -Dmaven.compiler.verbose=true and remove the else clause?

[kiszk]

sure, done

[kou]

Do we still need this?

[kiszk]

No, use the original setting. Done

We hold off merging this until we come to consensus on https://lists.apache.org/thread.html/r3d4ab3ccc8db7a7a68baa727bf9b6911930b61609c0faaed14e2b773%40%3Cdev.arrow.apache.org%3E .

@emkornfield @kou Is it ok to merge this PR now? Or, do we still hold off for a while?

[emkornfield]

Yes, I think so. I'd still like to update the contributor guidelines to make it clear what the level of support we are aiming for in each language (I hope to get to it tonight but if I don't it might take me a few days), but I think CI should be harmless. @kou it looks like you are happy with this PR?

[kou]

Yes.
But I want to confirm that this still works with the latest master before we merge.
@kiszk Could you rebase this on the latest master?

[kiszk]

@emkornfield @kou Thank you. I want to merge only this PR for CI. We should still hold off other PRs.

I rebased with master branch and confirmed it works well.

[kou]

Thanks.
I'll merge this.
