Create ppd_cache directory if it doesn't exist.  Also, rename it to CamelCase to match the observed conventions of other things in /home/chronos.

The name change is safe because no one uses this directory yet.  No
one uses it yet because all the functionality that *would* use it is
failing because...the directory is never created.
