[PyQt] Build error in qpyqml_register_type.cpp

I have managed to find the problem, so here's a follow-up. The issue was
that my Qt was configured with the `-qtnamespace` option. While I was
working through configure options to build the library, adding this option
was suggested to me at some point - I don't remember exactly when. However,
PyQt build scripts are obviously incompatible with this, resulting in the
build error I described previously.

I ended up rebuilding Qt without the option - I don't see the warning from
configure anymore now, so this is no problem - and then PyQt built
perfectly.

Thanks
Oli
