landlock: split .special into .makeipc and .makedev
As discussed with @topimiettinen[1], it is unlikely that an unprivileged
process would need to directly create block or character devices. Also,
`landlock.special` is not very descriptive of what it allows.
So split `landlock.special` into:
* `landlock.makeipc`: allow creating named pipes and sockets (which are
usually used for inter-process communication)
* `landlock.makedev`: allow creating block and character devices
Misc: The `makedev` name is based on `nodev` from mount(8), which makes
mount not interpret block and character devices. `ipc` was suggested by
@rusty-snake[2].
Relates to #6078.
