Build fix: arm64: incomplete landlock_rule_type type

While building the arm32 compatibility syscall instrumentation for
arm64, the build fails because types related to `landlock` are unknown.

Fixes:

/root/lttng-modules/src/../include/instrumentation/syscalls/headers/arm-32-syscalls_pointers.h:1428:138: error: conversion to incomplete type
 1428 |  TP_FIELDS(sc_exit(ctf_integer(long, ret, ret)) sc_inout(ctf_integer(const int, ruleset_fd, ruleset_fd)) sc_inout(ctf_integer(const enum landlock_rule_type, rule
_type, rule_type)) sc_inout(ctf_integer(const void *const, rule_attr, rule_attr)) sc_inout(ctf_integer(const __u32, flags, flags)))
