software/monitor: Downgrade scipy for resolution

Donwgrade scipy to be compatible with the version of numpy pinned
in software/monitor - itself downgraded to be compatible with the
version of statsmodels currently pinned to 0.11.1. Upgrading this
will first require adjusting the code in slapos.toolbox that uses
statsmodels, as the next version has breaking changes in the API.
