env: preprend gst-build/prefix/etc/xdg to XDG_CONFIG_DIRS

So gst-build/prefix/etc/xdg/tizonia/tizonia.conf can be found.
Which one contains path to tizonia plugins. Useful when
compiling tizonia-openmax-il and installing it in gst-build
's prefix location:
  autoreconf -ifs
  ./configure --disable-player
              --without-libspotify
              --prefix=path_to_gst-build/prefix/
  make && make install

Allows the following to work:
  gst-launch-1.0 videotestsrc ! vp8enc ! omxvp8dec ! xvimagesink
