Remove QtWebKit4

[Christian Stadelmann]

qtwebkit (Qt4's WebKit binding) is full of hundreds of known CVEs and hasn't seen
a security patch in years. For the same reason, WebKitGtk has been removed from Fedora
[1]. How about a plan to do the same with qtwebkit?

I've already opened a bug report against qtwebkit [2] but it does not seem to have any
effect.
