[meta-xilinx] [PATCH] xsct-tarball: use fetcher cache

[Jean-Francois Dagenais]

Without it, whenever a build starts on a fresh tmp directory, the file
is actually downloaded from http://petalinux.xilinx.com each time. Even
though it might be in the local download dir or in the SOURCE_MIRROR_URL
specified mirror. This unnecessarily slows down build bootstrap and puts
burden on xilinx.com servers.
