      landlock: Use square brackets around "landlock-ruleset"

      commit aea0b9f2486da8497f35c7114b764bf55e17c7ea upstream.

      Make the name of the anon inode fd "[landlock-ruleset]" instead of
      "landlock-ruleset". This is minor but most anon inode fds already
      carry square brackets around their name:

          [eventfd]
          [eventpoll]
          [fanotify]
          [fscontext]
          [io_uring]
          [pidfd]
          [signalfd]
          [timerfd]
          [userfaultfd]

      For the sake of consistency lets do the same for the landlock-ruleset anon
      inode fd that comes with landlock. We did the same in
      1cdc415f1083 ("uapi, fsopen: use square brackets around "fscontext" [ver #2]")
      for the new mount api.

Changed the format of the landlock tracing. We need to update the strace
expected string to match.
