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!
