Resolve broken scikits.odes installation on self-hosted M-series ru…

…nner (pybamm-team#3785)

* Try fixing M-series runner tests

This is being done by adding SuiteSparse and SUNDIALS installations which might have been missing on the runner, which broke `scikits.odes`.

* Don't use Homebrew SUNDIALS, use LD_LIBRARY_PATH

* Don't use Homebrew to install SUNDIALS

* Force remove pip cache for `scikits.odes`
