tst-backtrace4: expand output even on failures
When debugging failures in this test, it's helpful to see as much output as possible. So rather than returning immediately, let the code run as far as it can. We still mark failures as soon as they happen. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
