setup: include additional packages in py2exe distribution

I'm attempting to reproduce the Inno installers on my local
machine. As part of auditing differences between installer output,
I noticed that the existing Inno installers include various 3rd
party packages.

There is no mention of this in the build instructions nor on
the wiki. This must be something that is done by the installer
producer.

This commit teaches setup.py to include these 3rd party packages
in py2exe's library. After this change, I am able to produce
Inno installers that have a nearly identical set of Python
modules.

It's worth noting that pywin32 is included even though it
probably shouldn't be. But including it is necessary in order
to achieve parity with existing Inno installers.

         - build Mercurial with --long-paths-support option
         - change HKLM\SYSTEM\CurrentControlSet\Control\FileSystem\
                  LongPathsEnabled to have value 1.

         yet aware of long paths support in the manifest (I think so at least).
         This does not stop mt.exe from embedding/merging the XML properly.
