stdenv/setup.sh: fix read -N 0 for bash 5
somehow `read -N 0` behavior changed in bash 5. `read -d ''` has identical behavior the purpose of the function is to read stdin and exit 1 on a null byte (i.e. if stdin is the content of a binary) (cherry picked from commit 5d0acf20f88b1820cb8b641cfc5a43e973122701)
