David f9bc7d18e2 test(libkernel_sys): run the fchdir search permission check on macOS 
The case that removes search permission from a directory and expects
fchdir to fail with EACCES, leave the working directory unchanged and
succeed again once search is allowed ran only on Linux. It now runs on
every host but Windows, with the POSIX headers it needs.
