run-make-check.sh: let ctest generate XML output

to enable XUnit plugin of jenkins to consume the ctest output and
publish it in the dashboard, we need to

* let ctest generate XML output instead of plain text output
* do not fail the test if any test case fails. this allows the publisher
  to do its job by checking the XML output.
* prevent ctest from compressing the output. see
  https://issues.jenkins.io/browse/JENKINS-21737
