Esteemed maintainers,

This commit cleans up the changes made by
fd3eac4dd774597d493e6d8aae7b1c2653070bc7 (which worked-around the issue of
repeated (wrap-program) calls creating wrappers of wrappers --- i.e.
..calibre-real-real-s --- by creating a manual 'wrap phase that did the
work of the standard 'wrap phase and also the runtime dependency resolution
of QtWebEngineProcess), based on the suggestion of the author of the commit
himself (https://issues.guix.gnu.org/43249#14).

For more information, please consult the discussions in
https://issues.guix.gnu.org/43249

Thank you
