Travis - use ctest built-in feature to verbosely log test failures

Setting CTEST_OUTPUT_ON_FAILURE will cause ctest to log all
output from failing tests (and only from failing tests).
This will reduce our ci output in case of failures as our
homebrew script 'afterfailure' would output all test logs
in case of failure not only the output of failed tests.
