Disable some Python bindings in {hxtorch,pynn-brainscales}

See merge request technical-coordination/project-internal/devops/platform/ebrains-spack-builds!195

This is a workaround for pysctrltp not detecting newer versions
of pybind11 correctly, and for `pyhxcomm` building a test binary linking
against stuff which requires linkage against libpython.
The real fix requires CR within the software stack and will only be
available later.
