New package: qt-webkit-2.3.4

The idea to have a separate qt-webkit package which builds with gcc6
is taken from the Arch Linux team's efforts:
https://git.archlinux.org/svntogit/packages.git/tree/trunk?h=packages/qtwebkit

This addresses #4748 the unsolvable(?) problems when trying to build the
shipped qtwebkit that comes with qt-4.7.8 with gcc6.
