last-working-dir: Use >! to overwrite $cache_file

Use ">!" to overwrite $cache_file in case noclobber is set. When noclobber is set, zsh will not allow the use of ">" to overwrite the contents of a file. Instead, it displays a "file exists" error. By using ">!" instead, we tell zsh to overwrite the file without complaining.
