Title: Ensure git_futils_mkdir won't mkdir root

This makes sure that `git_futils_mkdir` always skips over the root directory at a minimum, even on platforms where the root is not simply '/'. Also, this removes the GIT_WIN32 ifdef in favor of making EACCES as a potentially recoverable error on all platforms.
