    libctf: fix a comment typo
    
    ctf_dedup's intern() function does not return a dynamically allocated
    string, so I just spent ten minutes auditing for obvious memory leaks
    that couldn't actually happen.  Update the comment to note what it
    actually returns (a pointer into an atoms table: i.e. possibly not
    a new string, and not so easily leakable).
    
    libctf/
            * ctf-dedup.c (intern): Update comment.
