Nobody told the tools that log events with operation="symlink" exist.
Add this keyword to the list of file or network operations (I don't
expect network symlinks ;-) but keeping everything in that list makes
things easier than special-casing it.)
Also add the log sample and expected result to the libapparmor tests.
