landlock: Fix tracepoint fixed-width type names
The new Landlock tracepoints use UAPI-prefixed __u32 and __u64 names for callback arguments and record fields, including internal IDs that are not Landlock UAPI values. Typed BPF consumers see callback typedef names through BTF. Use the kernel u32 and u64 aliases before release so the tracepoint contract does not present internal values as Landlock UAPI types. This changes BTF-visible typedef spelling but not integer widths, calling conventions, tracefs formats, or record layouts.
