py-greenlet: updated to 1.1.2

1.1.2
- Fix a potential crash due to a reference counting error when Python
  subclasses of ``greenlet.greenlet`` were deallocated. The crash
  became more common on Python 3.10; on earlier versions, silent
  memory corruption could result.
- Fix a leak of a list object when the last reference to a greenlet
  was deleted from some other thread than the one to which it
  belonged. For this to work correctly, you must call a greenlet API
  like ``getcurrent()`` before the thread owning the greenlet exits:
  this is a long-standing limitation that can also lead to the leak of
  a thread's main greenlet if not called; we hope to lift this
  limitation. Note that in some cases this may also fix leaks of
  greenlet objects themselves.
- Python 3.10: Tracing or profiling into a spawned greenlet didn't
  work as expected.
