pypy derivations produce broken pypy installation for x86_64-linux

Describe the bug

The x86_64-linux pypy installations provided by the pypy3.10 and pypy3.9 derivations are broken such that `python -m sysconfig` fails with `ModuleNotFoundError: No module named '_sysconfigdata__linux_x86_64-linux-gnu'`. This causes lots of other functionality in the standard library to fail, e.g. `python -m venv foo`, `python -m ensurepip`, etc. Click to toggle example trace from a GitHub Actions 'ubuntu-latest' runner

Steps To Reproduce

nix-shell -p pypy3.10 -p pypy3.9
pypy3.10 -m sysconfig
See error and nonzero exit status
pypy3.9 -m sysconfig
See error and nonzero exit status

Expected behavior

'sysconfig' imports successfully, command exits 0

nix-env --version output

nix-env (Nix) 2.18.1

I consistently reproduce this on GitHub Actions' ubuntu-latest runners.

Locally I only have an aarch64-darwin Mac to test on where I have nix-darwin installed, and I do not reproduce this there.
