[PATCH 2/4] modpost: make updating the symbol namespace explict

[Matthias Maennich]

Setting the symbol namespace of a symbol within sym_add_exported feels
displaced and lead to issues in the current implementation of symbol
namespaces. This patch makes updating the namespace an explicit call to
decouple it from adding a symbol to the export list.
