Add back the namespace_packages arg in setup.py.

Improves #1296.

The problem: in the previous patch, we tweaked the __init__.py files to use
namespaces, but no longer declared ourselves as a namespace package. The
second half was unwise.

Note that this only comes up when installing protobuf alongside another
package that also installs into the google namespace; as of right now, the
only PyPI package that does is googleapis-common-protos, though the GAE SDK
also uses google.appengine. Installing either or both of those alongside this
package now works.

The case that still remains is the upgrade path, which is also what worried me
in #713. It seems that if protobuf 2.6.1 is installed, there's no way to
safely upgrade that to work with a newer protobuf. However, `pip uninstall` &&
`pip install` does the trick.
