Weaver tests are flaky on PyPy

They are skipped for now but would be nice to have them work reliably if possible. I guess we also have slow installing times due to missing wheels since failing runs took more than 10 minutes.

Start with tests/opentelemetry-test-utils/tests/test_weaver_live_check.py and tests/opentelemetry-test-utils/src/opentelemetry/test/weaver_live_check.py, then reproduce the skipped Weaver tests under PyPy. Trace the process startup and /health readiness path around the reported exit code -6 and epoll error. Done means the Weaver tests run reliably on PyPy without the current skip.
