  Fix 21567 - build.d install fails for sources from official releases (#12144)

  The official releases only include the configuration of the current OS
  in the root directory instead off multiple configurations nested in
  the `ini` folder.

  This commit checks whether the `ini` directory exists and falls back to
  the expected path for releases otherwise.
