Added script hooks for unfinished custom configurations.

- These scripts default to calling out to scripts of the same name as
  defined by the custom configuration project (i.e.
  `$MAC_OS_CONFIG_PATH`).
- This helps ensure the scripts in this project can be run
  appropriately even if the custom configuration project hasn't fully
  implemented all scripts yet.
- This also helps illustrate what scripts are necessary when creating a
  custom configuration.
