Why would you want to use updated fonts in Emacs but an older version
in other applications?

Anyway, try making a custom font configuration file to the lines of

    <?xml version="1.0"?>
    <!DOCTYPE fontconfig SYSTEM "fonts.dtd">
    <fontconfig>
      <include>/etc/fonts/fonts.conf</include>
      <dir>/foo/dejavu</dir>
    </fontconfig>

and starting Emacs with the FONTCONFIG_FILE environment variable
pointing at that.
