archivers/py-bup: Update 0.32 => 0.33.10

Commit log:

• The big change in the 0.33 series is that bup is now a real binary linked against libpython (selected via python-config).
• Configure no longer uses a plain PYTHON= variable; it uses BUP_PYTHON_CONFIG.
• BUP_PYTHON_CONFIG=${PYTHON_CMD}-config so configure/build uses the port’s Python (critical on 3.12+).
• Fixed the duplicate RUN_DEPENDS= that previously overwrote the real dependencies.
• Strip both the new bin/bup (lib/binary and the remaining *.so helpers.
