   This is used for argument parsing in the retry script, however we don’t use the script with any arguments. So remove the unused code, and the dependency on gnu-getopt.

   This came up in the context of adding new CI jobs, where gnu-getopt might not be available, or working properly. It seemed easier to just remove the unused code, than look for more workarounds.

   Was about to suggest to re-write this in Python or Rust at this point, but python is not installed yet, and installing it should be done with a re-try, so this is probably the only place where Bash makes sense for now.
