extensions: avoid including `__index__` in the disabled extension list

This generated module contains a dictionary of all bundled extension names and
their help for builds that cannot enumerate extensions in the filesystem.

The disabled list gets displayed in `hg help extensions`, and is also used by
`setup.py` to populate `__index__.py` when building.  I haven't seen it sneak
into either py2exe or PyOxidizer builds, but it does show up when running tests
locally after having created an installer.
