config: removal of s390x

[rnveach]

This removed s390x because travis is having issues running it and also synchronizes configuration with what is found in eclipse-cs.

Comparison at #928 (comment)

Coverage remained the same at 98.798% when pulling a2cd7bf on rnveach:config_test into 03d5a0b on sevntu-checkstyle:master.

It appears upgrading tycho fixes this in the current CI run:
https://app.travis-ci.com/github/sevntu-checkstyle/sevntu.checkstyle/jobs/587030914#L1471

I am comparing output from previous runs.

[rnveach]

Old run: https://app.travis-ci.com/github/sevntu-checkstyle/sevntu.checkstyle/jobs/586914601#L1513
New rerun to confirm it continues to pass and it does.

The new run has the following:

While the old run was just:

Output looks similar to old run and travis passes. I will fix up PR.
