CI: Add logs to zloop workflow

On failure attempt to include the most relevant portions of the ztest logs in the CI output. This full logs are still available for download but often a backtrace and the last output is enough. Install libunwind to improve the odds of a useful backtrace. Signed-off-by: Brian Behlendorf <[email protected]>
