vsp-lib: Capture the kernel log messages in test log files
It can be useful to capture kernel log messages in test log files for diagnostic purpose. Add a simple mechanism to do so by capturing the full kernel log at the end of the test. The kernel log is cleared first before starting the test to avoid capturing unrelated messages. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> --- Changes since v1: - Don't clear the kernel log
