Subject: [PATCH] Linux: CMake: Omit linking browser related dynamic libraries

We've already had a mechanism in place which loads these libraries, such
as libwebkit2gtk-4.1.so, only if they are available on the system during
runtime. This way we can run with either version 4.1 or 4.0 of the
library depending on which one is available.

It's also possible to run apps on headless systems with the relevant
features being effectively disabled in such situations.
