Skip a too-unstable test on s390x-linux
In the last 26-ish hours, it has failed 5 times: https://travis-ci.org/github/ruby/ruby/jobs/676497718 https://travis-ci.org/github/ruby/ruby/jobs/676480295 https://travis-ci.org/github/ruby/ruby/jobs/676103216 https://travis-ci.org/github/ruby/ruby/jobs/676057967 https://travis-ci.org/github/ruby/ruby/jobs/676055113
and I don't think anybody has been working on it right now. To make CI result report of s390x-linux useful, let's skip it until the test is improved to be more stable.
