Testlib/Windows: Output crash information on stdout instead of stderr.

Browse Source 
Make it easier to capture information about crashing tests in log files,
since it is not possible to do something like
foo > log.txt 2> errlog.txt
on Windows.
Adapt selftest.

[ChangeLog][QtTest][Important Behavior Changes] Crash/exception
information is now logged to standard output on Windows.
