refactor: improve conditional statements in install_config.sh

The code changes refactor the conditional statements in the `install_config.sh` file. Instead of checking if `${shortname}` is equal to "dst" or "arma3", it now checks if `${clustercfgdir}` or `${networkcfgdir}` are not empty, respectively. This improves readability and maintainability of the code.
