I have attached a patch that disables support for loading the Widevine
plugin, and also removes unused bundled software from the source based
on a whitelist, similar to ungoogled-chromium's
%PRESERVED-THIRD-PARTY-FILES.

It removes some 300+ MiB from the uncompressed sources.  The snippet
will require some adjustments for every new version of QtWebEngine
however, I can help out with that when required.

Patch 1/2 is a slightly "cleaned up" version of Mike's latest patch,
fixing some cosmetic issues, and makes it respect the daemons requested
number of build cores.

With these changes, I think the package is ready to go.  \o/
