travis-ci: run tests with '-x' tracing

szeder · gitster · commit aedffe952508 · 2018-02-28T12:57:51.000-08:00
Now that the test suite runs successfully with '-x' tracing even with
/bin/sh, enable it on Travis CI in order to

  - get more information about test failures, and

  - catch constructs breaking '-x' with /bin/sh sneaking into our test
    suite.
