This fixes part of PR 55041 by updating the hash table printers to
account for Francois's recent changes.

        PR libstdc++/55041
        * python/libstdcxx/v6/printers.py (Tr1UnorderedMapPrinter): Update
        to handle hashtable as member of unordered_map not base class.
        (Tr1UnorderedSetPrinter): Likewise.

Tested x86_64-linux and committed to trunk.
