macOS-only failures in CI with RDKit visualization

See original GitHub issue

I can’t reproduce this locally (macOS, Python 3.9) with the same versions of cairo, pycairo, and rdkit, the latter of which was recently bumped to 2021.09.5. I checked the RDKit and its feedstock’s issue tracker and nobody else has reported it yet.

I somehow did not have the thought of looking as far as the fontconfig feedstock, where I found a familiar face already tracked this down and reported it! https://github.com/conda-forge/fontconfig-feedstock/issues/54

Seems to actually be fixed after https://github.com/conda-forge/conda-forge-repodata-patches-feedstock/pull/248
