[pybsddb] berkeleydb segfaulting with Python 3.13

[Jacob Henner]

berkeleydb is segfaulting on Arch Linux amd64, with Python 3.13 and
either libdb 6.2.32 or libdb 5.3.28. Both Python 3.13.0 and 3.13.3 were
confirmed to be affected. 3.12.10 is not affected.

This reproducer [1] (for a separate issue) will trigger this segfault,
but it seems to be trivially invoked by `berkeleydb.hashopen(...)`
without any additional steps.
