[sdk/kdesrc-build/docbook_historied_per_file] doc/kdesrc-buildrc: Add support for --no-build-when-unchanged

Git commit d8fb6b82a84f32232294ef35f16cf2f74f269474 by Andrew Shark.
Committed on 16/01/2024 at 11:49.
Pushed by ashark into branch 'docbook_historied_per_file'.

Add support for --no-build-when-unchanged

This option was mistakenly not marked as negatable.
Adding the negatable form allows to override the `true` value set to this option from config.

Fixes: #351
