Disable build for pygtk2 module

The pygtk2 module is orphaned and will be retired from Fedora.
Also, there is a binding for zbar that claims to support both
python2 and python3:
	https://github.com/zplab/zbar-py

Ok, this is currently not packaged on Fedora, but it should be
easy to install it via pip. So, it may not make much sense to
change zbar to have a pygtk3 binding.
