landlock: Use square brackets around "landlock-ruleset"

Browse Source 
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.
