qt4: unconditionally disable gstreamer 0.10 support in qt webkit
Previously it was auto-detected in a broken way, which was causing build errors
for qt-mobility. Qt4 build will fail if some gstreamer 0.10 packages are
available at build time, but not all. It will not fail if none of
the packages are available or if all of them are available. We can't guarantee either,
hence this patch.
