Fix for failing compile-runtime-tests (#18569)

compile-runtime-tests is looking for python3, but $(env python3) will return error (no `/usr/local/bin/python3`); if this is the case, create a symlink from 3.6 or 3.7 to /usr/local/bin/python3 so it works. We already have this listed in `SHEBANG_FILES` for the port.
