CI: avoid mixing caches from different OSes

This is a bug in setup-ocaml@v3 ocaml/setup-ocaml#839 Work it around by defining our own cache prefix based on runner OS version. Unfortunately the version itself doesn't seem to be available as a variable in GH actions. There is 'runner.os', but that is just a generic Linux, there is 'matrix.os', but that is only present when using a matrix, and there is '..container' which is only present when containers are used.
