[eog-plugins] postasa: Stop using deprecated g_type_class_add_private

[Felix Riemann <friemann src gnome org>]

commit b9a5de5f9dfc750e4a3b5af0541f9110c249aa3e

    postasa: Stop using deprecated g_type_class_add_private
    
    Use G_ADD_PRIVATE instead. Upcoming glib releases will mark
    g_type_class_add_private as deprecated so this will avoid a
    deprecation warning during build with these versions.
