ktest: Show times for build, install, boot and test
Seeing the times for how long a build, install, reboot and the test takes is helpful for analyzing the test process. Seeing how different changes affect the timings. Show the build, install, boot and test times when at the end of the test, or between each interval for tests that do those mulitple times (like bisect and patchcheck).
