Update pdfsqueeze to r4 to pick up licensing information.

This makes licenses.py happy.

pdfsqueeze changes: http://code.google.com/p/pdfsqueeze/source/list

r4 Added copying file + minor change to preserve date stamps.

r3 Fixed up inputs and outputs on script phase.
   This modifies a file under xcodeproj, which should not affect Chromium
   (we have a gyp file for pdfsqueeze).

This passes the mac trybot, so I think I'm ready to check in.
