[PATCH 3/4] Config: Refactor mastering packages

[Michael Tremer <michael.tremer@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 4364 bytes --]

Those are now created in their own temporary directory, so that
no other files can be included by accident.

We also package with fewer temporary files.
