Add OSX binary symlinks for 10.13

[illicitonion]

dea601c3bea992a5c7886d3541ad2003cce1025d and d8fe0801e0892c09e786caf5098d082efe89609e only added symlinks where the type was already a file. If the target was already a smlink, nothing was added.

This was generated with:

find $PWD/build-support/bin -wholename "*/mac/10.12/*" -type l | {
  while read binary
  do
    newbin=${binary/\/10.12\//\/10.13\/}

    binary=$(basename ${newbin})
    newdir=$(dirname ${newbin})
    version=$(basename ${newdir})

    rm -rf ${newdir}
    mkdir -p ${newdir}
    cd ${newdir}
    ln -s ../../10.12/${version}/${binary}
  done
}

exactly the same as d8fe0801e0892c09e786caf5098d082efe89609e but with -type l instead of -type f.
