opencv-3.1: get ippicv from the nix store

If ippicv can't be found in the directory:

  3rdparty/ippicv/downloads/${platform}-${md5}

it will be downloaded instead. Commit 7fedbe7 accidentally swapped the
md5 with the sha256 causing ippicv to be downloaded each time opencv
gets build. This patch fixes that.
