[bug#35866] [PATCH] gnu: qtwebengine: Do not use 3rd party libraries.

[Mike Rosset <mrosset@bufio.org>]

Most in tree third party libraries are now linked to Guix libraries.  There
are a few Guix libraries that break the build or are not automatically
detected these are now documented in the input expression.

gnu: qtwebengine: PDF and printing support is now disabled.

PDF and printing requires pepper plugins. which is not enabled.
