Resolve Calibre run-time dependency |

Esteemed maintainers,
Currently, Calibre can't open .epub files unless `qtwebengine` package is also available in one's $GUIX_PROFILE. Neither can the stand-alone `ebook-viewer` program supplied with Calibre. It exits with the complaint: "Could not find QtWebEngineProcess".
Attached is a patch to fix the issue. QtWebEngineProcess is now made available to all Calibre binaries via QTWEBENGINE_PATH set during a new 'wrap-program phase introduced with the patch.
Thank you

thanks to both of your for your patches! I just pushed Brendan's, which
wraps only once at the price of copy-pasting from another package. I confirm
that it works, also to click on an epub file from within calibre. Closing
the two bugs asking about qtwebengine.
Concerning the update, is mathjax a required input now, or could we just
leave it out and update nevertheless?
