ftrace/selftests: Add softlink to latest log directory
When I'm debugging something with the ftrace selftests and need to look at the logs, it becomes tedious that I need to do the following: ls -ltr logs [ copy the last directory ] ls logs/<paste-last-dir> to see where the logs are. Instead, do the common practice of having a "latest" softlink to the last run selftest. This way after running the selftest I only need to do: ls logs/latest/ and it will always give me the directory of the last run selftest logs!
