Fix 32bit CI

[benjeffery]

Latest cython breaks compilation of h5py.

Is it time to drop h5py? It's years since anyone used the legacy formats, I'll bet, and they can install old versions of tskit if needs be.

Ok, so after updating the 32bit docker image as it was on 3.7 and that was causing issues, numba now won't build as it needs llvm. However it needs specifically llvm version 10, which is no longer in the main ubuntu ppa.
On searching I see I should be able to get it from universe: https://pkgs.org/download/llvm-10
Will try that tomorrow.

Oh jeez, fun times

An alternative here might be to use the same workaround we have for 311 and skip the tests that require lshmm

Went a bit round the houses here, but this seems to work for now.
