__ini_value: moved awk script generation to gencode-remote
The script generation of the awk script was moved from `files/gen-awk.sh` to `gencode-remote` because the size not really matters. If the file does not exist, it will be created by a predefined template via an here-doc to avoid a big awk-script where it is not needed.
