ci: avoid cmake -Hpath

This is an undocumented option similar to the `-Spath' option introduced
in cmake 3.13.
Replace all instances of `-Hpath' with `-Spath' in macos workflow.
Replace `-H. -Bpath' with `mkdir path; cd ./path; cmake ..' in zuul
scripts since it runs an older version of cmake.

Fixes #9008
Closes #9014
