setup: properly install build_hgextindex for py2exe builds

Because the hgbuild class has a private copy of build.sub_commands,
modifying build.sub_commands from this code effectively resulted
in a no-op. Registering the sub-command on hgbuild actually results
in the sub-command running when building Mercurial.
