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.
