[gtk-vnc] rpm: disable python binding build on Fedora and future RHEL

[Daniel P. Berrange <dberrange src gnome org>]

commit 0efe46648414e91ca1ec4f913ecb825231d745cd
Author: Daniel P. Berrangé <berrange redhat com>

    rpm: disable python binding build on Fedora and future RHEL
    
    The python binding only works for GTK2 and Python2, both of which are
    slowly going away. It is still possible to access the library from
    any Python using GObject introspection dynamic binding.
