Make cosmocc 100x faster on MacOS

This change upgrades to superconfigure z0.0.23 which fixes an issue
where the compiler had harmless /home/... paths baked-in, which are
normally only present in the build environment, and usually skipped
over. Sadly on MacOS calling fstatat() on these paths would lead to
cloud file system ops that caused system calls to take a long time.
