tests: record more stderr with --write-junit-xml in case of failure

Browse Source 
Sometimes, failures in a test case are actually caused by issues in
earlier test cases.

To make it easier to see those issues, let's attach the output from
before the failing test case (i.e. stdout/stderr since the previous
failing test case, or the start of the test script). This will be
visible in the "Attachments" of the details of the failed test.
