gtkbuilder: wrong usage of gtk_buildable_custom_tag_end

Submitted by Nubosch

Description

gtk_buildable_custom_tag_end [1] expects to get called with gpointer* but gets passed data->subparser->data [2] from subparser_end() which is defined as gpointer [3].

fixing this in either direction may break existing users in interesting ways but I would expect the interface definition to be respected.
