Tobias Bergkvist 228d451e03 makeBinaryWrapper: Fix chdir golden test for darwin
On macOS, /tmp is a symlink to /private/tmp. When performing cd /tmp, and checking cwd - it won't match since it follows the symlink.

This caused test breakage on macOS but not Linux. Instead, use a folder which is not a symlink, and consistent across Linux and macOS.
