setup.py: fixing version info for Windows hg.exe (py2exe)

Fixes

  warning: py2exe: Version Info will not be included:
    could not parse version number ...

which was seen when doing nightly builds. hg.exe files
of nightly builds did not have any version info resoure,
which may cause problems with installers.

Also setting a copyright string for the version resource
(was missing).
