CI: macos runners segfault failing on openmm tests

[IAlibay]

Expected behavior

All CI tests work as expected.

Actual behavior

CI is failing on macos runners with very unspecific segfaults.

See: https://github.com/MDAnalysis/mdanalysis/runs/5398923069?check_suite_focus=true as an example.

Apparently this might be related to: openmm/openmm#3491

Although it is oddly timed with py3.10 openmm support having been added yesterday.

Issue exists upstream: openmm/openmm#3495

My next steps will be to pin to the 7.7.0 build 0 and see if that'll fix things temporarily. Hopefully a fix will come soon.

build 1 has been marked as broken upstream
