    doc-postprocess.pl: Un-break tag file references
    
    * util/doc-postprocess.pl: For some reason, recent versions of
    Doxygen output the full path to referenced tag files.  This is
    bad since it breaks doc-install.pl, and also because it leaks
    local path names into source tarballs.  Thus, strip the directory
    prefix here.
