Subject: gnu: webkitgtk: Fix the build.

This is a followup to commit 8797a07ac0c2f2cce93b6642942a2654eaec1c69.

* gnu/packages/webkit.scm (webkitgtk)[arguments]: Add "-DUSE_SOUP2=ON"
to the configure flags.  Add the 'prepare-build-environment' phase,
which arranges to use clang for compilation.
[native-inputs]: Add clang-11.
[inputs]: Add lcms.
