change using circular imports between `ctypes/__init__.pyi` and `_ctypes.pyi` in `typeshed` crashes `pytype` testing on CI

[junkmd]

In typeshed repository, I am trying to write type stubs as close as possible to the implementation, so I migrated some stuffs from stdlib/ctypes/__init__.pyi to stdlib/_ctypes.pyi.
And I used circular imports for annotations.

But pytype testing on CI was failed.

See python/typeshed#8643.

Are there any plans for fixes?

I'll take a look.

This is luckily an easy fix. The issue is that pytype has its own _ctypes stub, because it didn't exist in typeshed. I'll copy over the RTLD_GLOBAL and RTLD_LOCAL constants for now. Once we've updated pytype's typeshed pin in a few weeks, I'll be able to delete our copy of _ctypes altogether.

@rchen152
Thank you for response.

As soon as I confirm this fix completed, I will make the changes to typeshed.
