Deal with failing Pyston benchmarks under 3.11.

[ericsnowcurrently]

When I ran the pyston benchmarks against 3.11 on our internal machine, only 3 of the 12 benchmarks ran successfully. The failures need to be resolved.

succeeded:

• json
• pycparser
• thrift

failed dependencies:

• aiohttp - yarl, uvloop
• djangocms - Pillow
• gevent_hub - greenlet
• gunicorn - yarl, uvloop
• kinto - uWSGI (Build failure with CPython main (3.11). unbit/uwsgi#2365)
• mypy - typed-ast
• pytorch_alexnet_inference - torch (pinned version is unsupported)

(Aside from uWSGI, all the dependencies should be fixed now and need their pinned versions updated.)

failed during benchmark run:

• flaskblogging - connection closed unexpectedly
• pylint - using inspect.formatargspec() (removed in 3.11)

This is already covered by #175.
