[PATCH RFC 2/4] landlock: implement memfd detection

Add is_memfd_file() function to reliably detect memfd files by checking for "memfd:" prefix in dentry names on shmem-backed files. This distinguishes true memfd files from regular shmem files. Move domain_is_scoped() to domain.c for reuse across subsystems. Add comprehensive kunit tests for memfd
