Fix build with rpm 4.20

QtWebKit's qmake files do some "clever" processing of the current directory
using qmake's replace() function to determine some (sub)paths.
However, the build dir was changed in 4.20 and now includes the package
name/version in the path.
In our case, the version "4.8.7+2.3.4" in particular breaks the build, as '+'
has a special meaning in a regexp (but of course this would happen with other
special characters as well).

These strings need to be escaped before passing them as pattern to replace().
