PyPy's internal packages leak through and pip-sync tries to uninstall them

On PyPy, rye sync makes a bit of a mess

Found existing installation: cffi 1.15.1
Not uninstalling cffi at /Users/mitsuhiko/.rye/py/[email protected]/lib/pypy3.9, outside environment /Users/mitsuhiko/hello-pypy/.venv
Can't uninstall 'cffi'. No files were found to uninstall.
Found existing installation: greenlet 0.4.13
Not uninstalling greenlet at /Users/mitsuhiko/.rye/py/[email protected]/lib/pypy3.9, outside environment /Users/mitsuhiko/hello-pypy/.venv

Found existing installation: readline 6.2.4.1

It's because cffi and a few others are installed into lib/pypy3.9 and are picked up:

$ ryed run python -c 'import cffi; print(cffi.__file__)'
/Users/mitsuhiko/.rye/py/[email protected]/lib/pypy3.9/cffi/__init__.py

I also think that rye is now unable to install cffi or any of such dependencies. These internal dependencies also show up in pip freeze:

$ ryed show --installed-deps
